It's differential geometry, right? Dennui (talk) 17:38, 4 July 2020 (UTC)

I am asking because I owe a lot to the late Robert Osserman. Dennui (talk) 17:47, 4 July 2020 (UTC)

Lots of red links:


 * Chern–Osserman inequality
 * Osserman conjecture in Riemannian geometry
 * Osserman manifolds
 * Osserman's theorem
 * Nirenberg's conjecture

This makes me sad. Dennui (talk) 17:49, 4 July 2020 (UTC)

I would try to create them by myself, but I am just an undergraduate student, these things are too hard for me. Dennui (talk) 17:49, 4 July 2020 (UTC)

Would you be interested in creating those articles? I can help you in other things, about Wikipedia's rules, which I know well. Dennui (talk) 17:50, 4 July 2020 (UTC)

P.S. I owe a lot to him because of the three math books he wrote: Two-Dimensional Calculus, A Survey of Minimal Surfaces and Poetry of the Universe: A Mathematical Exploration of the Cosmos. They all made a great impression on me. Dennui (talk) 17:52, 4 July 2020 (UTC)


 * It's differential geometry and analysis. I'm not completely sure what each of those topics is supposed to be; "Osserman theorem" and "Nirenberg conjecture" are a little vague. Osserman's most widely cited papers are:
 * * Osserman, Robert. On the inequality Δu≥f(u). Pacific J. Math. 7 (1957), 1641–1647.
 * * Osserman, Robert. The isoperimetric inequality. Bull. Amer. Math. Soc. 84 (1978), no. 6, 1182–1238.
 * * Osserman, Robert. Bonnesen-style isoperimetric inequalities. Amer. Math. Monthly 86 (1979), no. 1, 1–29.
 * In general it's much easier for me to edit pre-existing things than to create new articles from scratch. I'd be happy to follow any requests and make any contributions I can to articles that are already there, it's just too much work for me to create them myself. "Keller-Osserman problem" (following his 1957 paper) could be a good wikipedia article. Gumshoe2 (talk) 19:06, 4 July 2020 (UTC)


 * Okay! I will create the articles, and they will be a mess, but I will wait maybe someone can fix them. This is the Wikipedian spirit, hahaha. ^^ Dennui (talk) 19:09, 4 July 2020 (UTC) Thank you!

By the way, I am good at creating biographies.. If you want some mathematician covered here, I can try. :D Dennui (talk) 19:11, 4 July 2020 (UTC)

I've just created this one: https://en.wikipedia.org/w/index.php?title=Antoine_Song&action=history Dennui (talk) 19:12, 4 July 2020 (UTC)

I've undone an edit of mine, because I never took any course in analysis: https://en.wikipedia.org/w/index.php?title=Classification_of_discontinuities&diff=prev&oldid=951169724 Dennui (talk) 19:16, 4 July 2020 (UTC)
 * What do you think about it? Should I have kept it? Dennui (talk) 19:16, 4 July 2020 (UTC)

By the way, the one variable calculus articles on the english wikipedia are REALLY bad... I've tried to improve the one about the chain rule: https://en.wikipedia.org/w/index.php?title=Chain_rule&type=revision&diff=950737064&oldid=945984804 19:18, 4 July 2020 (UTC) — Preceding unsigned comment added by Dennui (talk • contribs)

 * I don't have too many opinions on what should be in the intro-undergraduate articles, maybe you should check in on the wikiproject-mathematics main discussion pages.


 * I'm kind of wary of having too many articles on current young mathematicians... I might suggest articles for Joseph Sampson (Eells-Sampson's paper is one of the most significant in differential geometry) and Doris Fischer-Colbrie (she only wrote three papers but each is significant, especially the one with Schoen). YanYan Li and Wei Ming Ni both definitely deserve articles. Gumshoe2 (talk) 19:30, 4 July 2020 (UTC)


 * Also Joel Spruck and Basilis Gidas Gumshoe2 (talk) 19:32, 4 July 2020 (UTC)


 * Hiroshi Fujita, major contributions are two papers with Kato on the Navier-Stokes equations and his paper "On the blowing up of solutions of the Cauchy problem for ut=Δu+u1+α" Gumshoe2 (talk) 19:39, 4 July 2020 (UTC)

Thank you for the recommendations. I will see what I can do. Sometimes it's TOO SOON to create an article about someone, because they need to meet PROF ~or GNG~ before I can create. Dennui (talk) 12:37, 5 July 2020 (UTC)

https://en.wikipedia.org/wiki/Wikipedia:Notability_(academics) https://en.wikipedia.org/wiki/Wikipedia:Notability

By the way, Nirenberg's conjecture is this: https://mathworld.wolfram.com/NirenbergsConjecture.html

Please, do you know If there is a way to create an article about Hiroshi Fujita? http://www.math.sci.ehime-u.ac.jp/~fujita/index.html https://www.genealogy.math.ndsu.nodak.edu/id.php?id=43556 I am not finding many sources. :( 189.6.234.6 (talk) 13:10, 5 July 2020 (UTC)
 * Assistant professors are almost always WP:TOOSOON for new articles, and that would apply to Fujita. —David Eppstein (talk) 16:39, 5 July 2020 (UTC)
 * Fujita's work is from the 1960s, dennui linked to an unrelated person of the same name. Fujita has two widely renowned and widely cited papers in PDE, cited over 1000 times. Is this sufficient for an article? Gumshoe2 (talk) 16:45, 5 July 2020 (UTC)

He is 91 years old. — Preceding unsigned comment added by 189.6.234.6 (talk) 13:12, 5 July 2020 (UTC)

I forgot to sign in... Dennui (talk) 13:13, 5 July 2020 (UTC)

I don't know if there is any available biographical material on Fujita, I only know that his two articles were well above the norm for impact. As for Nirenberg's conjecture, perhaps it could be nicely subsumed into a wikipedia page for "The Gauss map of a minimal surface". There are probably references in Osserman's survey book on minimal surfaces. Gumshoe2 (talk) 15:49, 5 July 2020 (UTC)
 * Fujita, Hiroshi; Kato, Tosio On the Navier-Stokes initial value problem. I. Arch. Rational Mech. Anal. 16 (1964), 269–315
 * Fujita, Hiroshi On the blowing up of solutions of the Cauchy problem for ut=Δu+u1+α. J. Fac. Sci. Univ. Tokyo Sect. I 13 (1966), 109–124

Please help me to make Osserman more famous? I LOVE his calculus book, I learned all I know about multivariate calculus there. Dennui (talk) 16:29, 5 July 2020 (UTC)
 * I'll do what I can to add good expositions, but I don't have any particular interest in amplifying particular mathematicians. Gumshoe2 (talk) 16:47, 5 July 2020 (UTC)
 * Okay. ^^ — Preceding unsigned comment added by Dennui (talk • contribs) 16:54, 5 July 2020 (UTC)

Done.

Hiroshi Fujita

We need someone who knows Japanese, to expand it from Japanese sources. Dennui (talk) 04:20, 6 July 2020 (UTC)
 * Great, I added a section for his contributions. Yoshikazu Giga, who studies PDE, is another person who certainly warrants a page. Gumshoe2 (talk) 05:31, 6 July 2020 (UTC)

Okay, I can keep trying to create them for you, but I need help with one of the following: "My heroes in mathematics are Robert Osserman, Ivan Niven, Howard Levi, Serge Lang and Vladimir Arnold."

DEAL? Dennui (talk) 05:34, 6 July 2020 (UTC)


 * I don't understand. I only want to improve some mathematical expositions on here, and I'm happy to do it for any page I can. What do you want me to do with those pages? Gumshoe2 (talk) 05:37, 6 July 2020 (UTC)

creating Levi's reduction process, expanding Topological Galois theory, creating Nirenberg's conjecture... That's what I want. Things like that. ^^ Dennui (talk) 05:39, 6 July 2020 (UTC)
 * I'd be happy to help but I'm just not familiar with these topics :( Gumshoe2 (talk) 05:55, 6 July 2020 (UTC)

GREAT!!! As we say in Portuguese: "combinado!" (it's arranged then). No problem not being familiar, if you make some mistakes someone will correct them. I will start another of your requests immediately. Dennui (talk) 05:58, 6 July 2020 (UTC)


 * I don't believe that's true, many mistakes are left on here for a long time, and even on high-traffic pages. I'll only write on things I have some personal expertise in. If you'd like, I could write a good section for Osserman's page surveying his major mathematical contributions.Gumshoe2 (talk) 06:07, 6 July 2020 (UTC)


 * Okay. I accept your offer. It's fair. Dennui (talk) 06:08, 6 July 2020 (UTC)

The next one to have an article here covering him will be: . . . Joel Spruck!!! Just wait, I need to drink some coffee. Dennui (talk) 06:03, 6 July 2020 (UTC)
 * Done... I will edit more later, my mother needs help now. Dennui (talk) 06:35, 6 July 2020 (UTC)

I think I'm done with that article. I don't understand the math. I am just an undergraduate student and english is not my native language you know... Dennui (talk) 08:07, 6 July 2020 (UTC)

Robert Osserman
Thank you very much for your contribution @ Robert Osserman article. Really appreciated. Thanks a lot. ^^ Dennui (talk) 07:15, 6 July 2020 (UTC)

btw, i forgot Jerry Kazdan in my list of heroes... his calculus textbook is amazing too, with a lot of basic linear algebra that is useful for calculus. Dennui (talk) 08:11, 6 July 2020 (UTC)

Hi, Gumshoe2. Sorry to take your time again. I will be creating the other biographies later today. I just wanted to ask your opinion on https://en.wikipedia.org/w/index.php?title=Tristan_Needham&type=revision&diff=966375181&oldid=949283418 Would it be a good idea to preorder it? Dennui (talk) 19:17, 6 July 2020 (UTC)


 * I don't know anything about it, sorry Gumshoe2 (talk) 00:53, 7 July 2020 (UTC)


 * Okay. I think I will buy it, it looks good. Dennui (talk) 03:26, 7 July 2020 (UTC)


 * Btw, I will create the articles "como combinado", but not today, because I am not feeling well today, okay? Dennui (talk) 03:50, 7 July 2020 (UTC)


 * Of course! All the names I gave were just suggestions. No pressure to do any of them Gumshoe2 (talk) 06:30, 7 July 2020 (UTC)

Classification of discontinuities
Hi! Is this information correct:?

"Intuitively, a function is continuous if (and only if) it has no breaks, jumps, vertical asymptotes, or wild oscillations." Dennui (talk) 07:39, 8 July 2020 (UTC)

do you think it would be a good idea to ask this one at mathstackexchange too? Dennui (talk) 08:40, 8 July 2020 (UTC)

I will make the question but i will understand if you don't have time or disposition to answer. ^^ — Preceding unsigned comment added by Dennui (talk • contribs) 08:11, 8 July 2020 (UTC)

i wanted to understand what it means that thr tangent line is the best linear approximation to the graph of a differentiable function at the point of tangency

I've looked in several books and I don't understand anything — Preceding unsigned comment added by Dennui (talk • contribs) 08:14, 8 July 2020 (UTC)


 * I recommend https://math.stackexchange.com, it's a great place to ask questions on any level Gumshoe2 (talk) 08:16, 8 July 2020 (UTC)
 * Ok, thannks! I will just complete the question:

where I wrote "linear approximation" read "affine approximation" ... I saw that they don’t use this much, but I thought about like the parabola and the tangent at the point (0,0) which is the x axis ... like how do i prove it is the best approximation? it's obvious but i want a proof

i will ask there... just need to polish my english. thanks Dennui (talk) 08:22, 8 July 2020 (UTC)

Is there any other mathematician you would like to be covered here? Dennui (talk) 07:49, 9 July 2020 (UTC)


 * Can't think of any others offhand Gumshoe2 (talk) 08:08, 9 July 2020 (UTC)


 * What about Charles Francis Doran? Dennui (talk) 09:44, 9 July 2020 (UTC)
 * His h-index is 21. It sounds enough for WP:PROF. Dennui (talk) 09:45, 9 July 2020 (UTC)

What is your opinion on this? Dennui (talk) 09:46, 9 July 2020 (UTC)

Maybe TOOSOON, the guy is young. Dennui (talk) 09:49, 9 July 2020 (UTC)

I’m not in Doran’s field but I’m not aware of particularly noteworthy achievements that go above the norm for a “good researcher”. I wouldn’t be able to contribute anything to his page Gumshoe2 (talk) 15:30, 9 July 2020 (UTC)
 * Yes, Doran looks like a successful full professor but nothing stands out beyond that to justify creating an article for him. Which criterion of WP:PROF do you think he passes? The usual one for most academics is #C1 but that's very difficult in mathematics because its citation counts tend to be low and Doran's are too low for that to work. —David Eppstein (talk) 16:54, 9 July 2020 (UTC)

Doris Helga Fischer-Colbrie
Please help me:

Doris Helga Fischer-Colbrie is a mathematician.

Education: Univ Calif, Berkeley Ph.D., 1978 member IAS supervision H. Blaine (Herbert) Lawson, Jr.

born in Vienna, Austria

married Richard Schoen, had two children

main pub:

Fischer‐Colbrie, Doris, and Richard Schoen. "The structure of complete stable minimal surfaces in 3‐manifolds of non‐negative scalar curvature." Communications on Pure and Applied Mathematics 33.2 (1980): 199-211.


 * Try this:


 * Doris Fischer-Colbrie is a ceramic artist and former mathematician. She received her Ph.D. in mathematics in 1978 from Universiy of California at Berkeley, where her advisor was H. Blaine Lawson.


 * Many of her contributions to the theory of minimal surfaces are now considered foundational to the field. In particular, her collaboration with Richard Schoen is a landmark contribution to the interaction of stable minimal surfaces with nonnegative scalar curvature. A particular result, also obtained by Manfredo do Carmo and Chiakuei Peng, is that the only complete stable minimal surfaces in $ℝ^{3}$ are planes. Her work on unstable minimal surfaces gave the basic tools by which to relate the assumption of finite index to conditions on stable subdomains and total curvature.


 * After positions at Columbia University and San Diego State University, Fischer-Colbrie left academia to become a ceramic artist. She is married to Schoen, with whom she has two children.

Done. This is my last edit, because they deleted Arnold Mathematical Journal when I created it. I will never pardon the English Wikipedia. They deleted my work. MathKeduor7 (talk) 19:30, 9 July 2020 (UTC)
 * Arnold Mathematical Journal has never actually been deleted. You created it in April 2015, and then redirected it to Vladimir Arnold yourself on the same day, but that redirection is not a deletion. It was created as a draft again by someone else in February 2019, and the draft was moved into article space on top of your old redirect in September 2019, but although that move involved a technical deletion of a redirect, it was not deletion of article content. So what are you talking about? —David Eppstein (talk) 07:18, 10 July 2020 (UTC)

ANI
Unsolicited advice: you are never going to get anyone to address the conduct issues if you do not restrain yourself from discussing the content issues there. You are not obligated to respond to every single thing everyone says, and ANI threads that become long walls of text become impossible to assess. --JBL (talk) 15:20, 15 August 2020 (UTC)


 * Thank you for the advice, I’ll take it into account. If it doesn’t go anywhere would it be bad form to repost it in a condensed form? I just want the problem to be taken care of Gumshoe2 (talk) 15:33, 15 August 2020 (UTC)


 * Well, there are currently two overlapping discussions open at ANI; I would certainly not repost anything as long as they are both open. I would counsel patience: no one is going to be harmed if this takes an extra week to sort out, and if the article gets worse then one can always go back to an earlier version.  My expertise is far from differential geometry, but it seems to me like there's a pretty clear consensus broadly for your position.  I don't know why the other editor is being so difficult about it, and why in particular they seem so impervious to recognizing the merits of other points of view.  It's easy to see why this is frustrating, but it's a very non-urgent kind of frustrating. --JBL (talk) 18:42, 15 August 2020 (UTC)

C. Robin Graham moved to draftspace
An article you recently created, C. Robin Graham, does not have enough sources and citations as written to remain published. It needs more citations from reliable, independent sources. (?) Information that can't be referenced should be removed (verifiability is of central importance on Wikipedia). I've moved your draft to draftspace (with a prefix of " " before the article title) where you can incubate the article with minimal disruption. When you feel the article meets Wikipedia's general notability guideline and thus is ready for mainspace, please click on the "Submit your draft for review!" button at the top of the page.

Your text about the sphere theorem is quite unbalanced. You mention various related works, but you did so in a rather selective way, playing up some contributions and downplaying others. 1.) Nguyen's contribution came much later than the Brendle-Schoen proof. Just look at the publication date. 2.) You mentioned Ben Andrews, even though he played no role whatsoever in the proof of the sphere theorem. 3.) You referred to Bohm-Wilking's work as "novel", but you did not refer to other work in that way. 4.) You did not mention Micallef-Moore's contribution. They introduced the concept of positive isotropic curvature in the first place. Without it, the proof of the sphere theorem would not have been possible. 5.) You did not mention Hamilton with one word, even though Hamilton's ideas underpin every single piece of work in that area. — Preceding unsigned comment added by Mikhail234 (talk • contribs) 04:40, 24 November 2021 (UTC)
 * 1.) Nguyen's independent work seems to be acknowledged in Brendle and Schoen's very article, from their very first arxiv post in 2007. So the publication date is misleading. 2.) That's fair, I only thought it would be helpful for identification since Huy Nguyen is a common name, even in math. I am fine with Andrews' name being removed. 3-4.) Fair points also. 5.) Hamilton occupies the first two sentences of the paragraph, and personally I have the very highest level of respect for him and his work. When writing I considered mentioning his maximum principle and his convergence criterion but couldn't decide how to fit them in concisely.


 * I will re-edit the page and you can see how you like it. I would recommend that it is better to edit constructively rather than to just remove blocks of text. If you can find a way to cite Hamilton for the relevance of his work, without unbalancing the flow of the text, I would be very happy to see it. Gumshoe2 (talk) 05:11, 24 November 2021 (UTC)

Re:
It is odd that you insist on writing the history of a problem that you are only superficially familiar with.

On a different note, your article on biharmonic maps is well written. You could contribute a useful article on Dirac harmonic maps or the bosonic string heat flow.

Mikhail234 (talk) 00:31, 29 November 2021 (UTC)
 * Thank you for the suggestions! Several years ago I studied all of the papers in question here, although I'm not familiar with priority disputes behind them. But regardless of who truly did what first, the key question for this website is what relevant sources say, and every major source I've seen gives equal priority for PIC to Brendle & Schoen and Nguyen.

You are currently edit-warring on wikipedia with unexplained reckless edits. If you continue removing WP:RSs in this way, you are likely to be blocked. Mathsci (talk) 17:12, 16 January 2022 (UTC)

Engaging (or not) with MathSci
In many cases it seems impossible. (At least, I routinely struggle to find a connection between what they write and what everyone else in a discussion is talking about.) I don't think telling them to e.g. "collect their thoughts" is likely to be fruitful; I would suggest just ignoring the incomprehensible bits. --JBL (talk) 01:07, 26 January 2022 (UTC)
 * Thanks for the comment, it is good to know I’m not the only one to struggle. But as you say, it is a consistent problem and so I think it is good to point it out, as politely and briefly as possible. He makes editing of pages on his watchlist very difficult, and his incoherence on the talk pages is a main part of it. So I do not think it is good to leave it unremarked on. Gumshoe2 (talk) 14:25, 26 January 2022 (UTC)
 * It hasn't always been thus. I think this may be related. --JBL (talk) 16:48, 26 January 2022 (UTC)
 * That is sad to see. But it remains that he makes editing extremely difficult, given that his strange and unresponsive commentary on talk pages is deeply related to editing activity. Ever since difficulties with him in 2020, I've consciously avoided editing any page if I see that he has ever made an edit there, no matter how much improvement I think it needs. The one time I gave it a try, one week ago, with fundamental theorem of Riemannian geometry, instantly created an unproductive headache. Gumshoe2 (talk) 17:17, 26 January 2022 (UTC)

Well, thanks for engaging with him on Schwarz triangle function despite this history. Maybe with our combined forces we can push past the issues with that article. Apocheir (talk) 22:56, 25 February 2022 (UTC)
 * Yes, I will help however I can. From what I can see, I agree with you on what should be done. Also, for the talk page, if you have not dealt with mathsci before, you should be aware that generally he will not acknowledge mistakes that he has made, and his only response to criticism is to deflect with long and essentially contentless responses. Gumshoe2 (talk) 23:05, 25 February 2022 (UTC)

Please stop your disruptive editing. If you continue to disrupt Wikipedia, as you did at Schwarz triangle tessellation, you may be blocked from editing. The title of the article has changed completely and its lede completely rewritten, pending major changes to the article which might take a few days. The "in-use" tag for major changes has been ignored by the user, contrary to the rubric. It appears that the user is doing their utmost to discourage edits to this article. Mathsci (talk) 22:46, 25 February 2022 (UTC)
 * If you are engaged in an article content dispute with another editor, discuss the matter with the editor at their talk page, or the article's talk page, and seek consensus with them. Alternatively you can read Wikipedia's dispute resolution page, and ask for independent help at one of the relevant noticeboards.

Undefined references
Hi, in this edit you introduced references to "Folland" and "Rudin" but did not define them. This adds the article to Category:Harv and Sfn no-target errors and means it is impossible for anyone reading the article to look up your references.

Berger's inequality for Einstein manifolds
Dear Gumshoe,

Just a heads-up that I redirected the page you PROD'ded and added a mention at Hitchin–Thorpe inequality. If you disagree with that, feel free to revert, as it is not really my field of expertise. Felix QW (talk) 19:02, 15 September 2022 (UTC)


 * Thanks, I don't understand well the choices between redirecting and deleting, so this is perfectly fine by me. In the sentence you added, I've removed reference to nomenclature "Berger's inequality" since it does not seem to actually be known by this. Gumshoe2 (talk) 20:56, 15 September 2022 (UTC)

Solutions to the viscid and incompressible Navier Stokes
Hi, The Navier-Stokes d.e. has been solved

I did observe that you removed my peer-reviewed reviewed by a well established institute, picked-up (republished) by the NASA, the harvard university and many other relevant web-sites and subjectively denoted as irrelevant and unverified. This has nothing to do with facts, but pure unsupported emotions by your side.

Why can i do not tell people that i have solved the most important open problem of physics?? It is a fact, and you do not have to see that as self-promoting because it is already been peer-reviewed by a well established insitute for physics. The growkudo.com website does bear my name, but i did not publish that!

So I just humblebly plead to you not put my name in a negative perspective in public without factual reasons. At this point i do not see the necessity to take legal steps against you.

But if you persist putting my name in a negative perspective i will reconsider that. Just do absorb the fact the Navier Stokes differential equation have been solved.

When i am acquainted with the Latex scripts used by Wikipedia better, i will setup an article-text better with formulas, figures and the like, by now only the updated comments and the peer-reviewed references.

Kind regards,

About neural network generated imagery
Hi! Was it just your personal opinion that it was an "unambiguously bad edit" in the article about G. Perelman?

I'm a newbie, and I don't really understand when it's really okay to suggest edits. Considering that the ability to edit is there after registration. I'd like to bring it up for discussion, but the last discussion was in 2020. I don't hold out much hope that the discussion will be promptly answered. Ian.donskov (talk) 10:16, 28 November 2022 (UTC)


 * Hi, my edit summary was somewhat rude; apologies for that. The answer is that computer-generated imagery has no encyclopedic value unless the article in question is about computer-generated imagery or something similar. You are very much free to bring up discussion wherever you like – depending on content, wikiproject math is more active and sometimes more useful than individual article talk pages – but I can almost guarantee you that in this case the consensus will be against such edits. You should also have at least a quick read through these editor help pages: and . Gumshoe2 (talk) 18:01, 28 November 2022 (UTC)

Martin Nowak at BLPN
Greetings re Martin Nowak at WP:BLPN. In this case, I do not recommend unarchiving the past BLPN thread. Multiple posts are normal but only one active discussion is ideal. Your re-post is enough. But for future reference. Without tools, you manually unarchive by finding the archiving diff (which you did), copy the code, edit the main article, and reinsert it chronologically where it belonged (probably near the top where fewer editors are looking unless they read histories). What really makes it an unarchive is that your edit summary says "unarchive: [reason]." You also have to remember to delete the corresponding code from the archive page. More useful for talk pages. Not usually necessary at WP:BLPN. Especially in the closed thread, thank you for explaining things well there! Cheers! JFHJr (㊟) 03:27, 17 May 2024 (UTC)
