Moebius plane
Your edit summary when you started the new article titled Moebius plane suggests that the spelling of the name was the only reason for creating the new article. If that's the reason, the proper way to do it is by using the "move" button, thereby keeping the edit history intact and avoiding having two article on the same topic. Michael Hardy (talk) 18:24, 19 January 2013 (UTC)
 * See also discussion here and here -- I've changed Moebius plane into a redirect, but by all means feel free to merge content into Möbius plane. --JBL (talk) 20:26, 19 January 2013 (UTC)
 * I undid that. You still have time to respond at Talk:Moebius_plane. RockMagnetist (talk) 20:45, 19 January 2013 (UTC)

I've gone ahead and merged the edit histories of the two articles. It is now approximately as user:Ag2gaeh left it. Some of the older material should doubtless be incorporated into the existing version. Michael Hardy (talk) 04:31, 20 January 2013 (UTC)


 * Sorry for causing so much trouble. I just wrote my first articls on Wikipedia. Yes, I am the author of the lecture note on planar circle geometries. This lecture note is not published anywhere, I just post it on my home page to make it available to people interested in this subject. So, it is up to more experienced Wikipedians to make the best of my contributions or even shut them down. The idea to use oe instead of ö came from my experience with English keyboards. If oe has to be changed I would ask any one to do it. I do not yet know how to find and replace within the Wikipedia editor.
 * Please, You should also have a look on my contributions on Laguerre and Minkowski planes and Benz planes. Ag2gaeh (talk) 12:13, 20 January 2013 (UTC)


 * Despite all the brou-ha-ha, you have not in fact caused very much trouble, and thanks for your contributions! It is very helpful to know that the notes you were posting to Wikipedia are your own.  I think the main point now is that it's silly to have two different articles on the same subject, and so the content you've created should be merged in a sensible way with the content of the existing article, especially to the extent that it includes content that can be cited to reliable sources.  Since I was the first person to remove the content you added, let me also be the first person to invite you to integrate it with the existing article.  One additional thing to be careful of: the LaTeX system in Wikipedia can be finicky, and some of the formulas you had posted were not compiling properly.  Thanks again!  --JBL (talk) 19:43, 20 January 2013 (UTC)


 * I agree - Wikipedia needs expert contributors, and I hope you will not be discouraged. By all means contact one of us if you have questions. To make it easier to add special characters, I suggest adding the edit toolbar to the default Wikipedia editor. You can do that as follows: click on Preferences at the top of any page, select the Editing panel, select Show edit toolbar, and save the changes (button at the bottom). Next time you have an article, you will have a menu from which you can select Special characters, and that has a table of characters. Just put the editor's cursor where you need a character, then click on the character. RockMagnetist (talk) 02:13, 21 January 2013 (UTC)


 * Thanks for Your patience. The contents of the present (and old version) had been nearly fully integrated in my version. Just the remark on finite Möbius planes and block designs, which is a very special view on Möbius planes, had been missing. It would have been no problem to add it. I just forgot to add it. Sorry! I probably underestimated the meaning of copyright. If You compare my contribution on Möbius planes with my lecture note You will recognize that it is not just a copy. But if I can't use my own words and the typical language of mathematics I should stop my contributions on this subject. By the way: You should also skip my contributions on Laguerre, Minkowski and Benz planes and on quadratic sets. Thank You, it was a try ! Ag2gaeh (talk) 07:28, 21 January 2013 (UTC)

If the concerns that some people expressed about copyrights on material added to this article is because of material being added by the person who owns the copyrights, there should be a standard way within Wikipedia to indicate that it's there with permission of the copyright owner. I don't off-hand know how that's done, but one could look into it. Michael Hardy (talk) 20:03, 24 January 2013 (UTC)

Your addition to Moebius plane has been removed, as it appears to have added copyrighted material to Wikipedia without permission from the copyright holder. If you are the copyright holder, please read Donating copyrighted materials for more information on uploading your material to Wikipedia. For legal reasons, Wikipedia cannot accept copyrighted text, or images borrowed from other websites, or printed material without a verifiable license; such additions will be deleted. You may use external websites or publications as a source of information, but not as a source of article content, such as sentences or images&mdash;you must write using your own words. Wikipedia takes copyright violations very seriously and persistent violators will be blocked from editing. Your article was a copy/close paraphrase of this article. RockMagnetist (talk) 23:43, 19 January 2013 (UTC)


 * Sorry, but I can't remember having edited the page Moebius strip. Ag2gaeh (talk) 12:20, 20 January 2013 (UTC)
 * Whoops! I corrected the message. RockMagnetist (talk) 16:41, 20 January 2013 (UTC)
 * If copyrighted material was added with permission of the copyright owner, who agreed to release it under whichever license Wikipedia now uses, there should be a regular procedure for making that fact known. I don't happen to know how that's currently done, but I doubt that it's hard to find out. Michael Hardy (talk) 00:53, 26 January 2013 (UTC)
 * My guess is that either Technische Universität Darmstadt or the math department own the copyright. Ag2gaeh could probably arrange for the university to donate it using the procedures in Donating copyrighted materials. RockMagnetist (talk) 01:17, 26 January 2013 (UTC)

Thank You for Your discussion. I try to find out who is the copyright owner of my lecture note. Facts: I wrote it while I was professor at the TUD and put it on my homepage at the Department of Mathematics of TUD. It is not published any where. All the pictures contained in my lecture note are made by my own using selfmade PASCAL-programs and the software fig. Ag2gaeh (talk) 09:00, 26 January 2013 (UTC)

The lawyer of TUD told me: There are no problems for an additional publication, if (1) there is no "third party funding" involved. This is not the case. (2) The usage of the material by TUD is not limited. This, I think, would be not the case. Ag2gaeh (talk) 08:17, 29 January 2013 (UTC)

It would be nice, if RockMagnetist could give an assertion of the copyright situation of my (partly deleted) contributions. Obviously, I am the copyright owner of my lecture notes, including the figures, which were (meanwhile) deleted by WIKIPEDIA. I ask WIKIPEDIA do undelete especially all the figures I uploaded in January. Ag2gaeh (talk) 16:19, 17 March 2013 (UTC)
 * Sorry, you were waiting for a response from me? I already told you what to do - follow the procedure in Donating copyrighted materials. A comment on your talk page won't resolve the copyright issue; you need to grant permission as described here and wait for their response. I can't do anything without that. I should add that I'm no expert on Wikipedia's copyright policy; if you're not satisfied with my response, you could try getting help here. RockMagnetist (talk) 20:53, 17 March 2013 (UTC)
 * I'm happy to see that you obtained the copyright. I hope your future contributions to Wikipedia go more smoothly! RockMagnetist (talk) 18:14, 19 March 2013 (UTC)
 * Dear RockMagnetist, meanwhile there is a permission for my lecture note (circlgeom.pdf) documented with [Ticket#2013031910004903]. The images (deleted by IneverCry) will be undeleted soon (see http://commons.wikimedia.org/wiki/User_talk:INeverCry#deleted_files). How can the article "Laguerre plane", version from January 19, article "Minkowski plane" (vers. January 19), "Benz plane" (vers. January 16) be restored and the current article "Möbius plane" replaced by the version contained in my sandbox ? These versions contain the images. Ag2gaeh (talk) 14:57, 22 March 2013 (UTC)
 * Once the images are restored, you could just click on the View history tab and undo the more recent changes. For Möbius plane, though, I'd recommend a different approach. Your articles are written in a style that is appropriate for a monograph but not well suited to an encyclopedia. Wikipedia articles on math should conform to the Manual of Style, particularly the Manual of Style for mathematics. I also strongly recommend that you read Make technical articles understandable. The current version of Möbius plane is more accessible than your version, and it would be better if you merged your text with it. Be aware, too, that one of the five pillars of Wikipedia is that anyone can edit, use, modify, and distribute its content. This may be easier to accept if the content is not a verbatim copy of your published work. RockMagnetist (talk) 16:36, 22 March 2013 (UTC)
 * Hi RockMagnetist, thanks for your tips. I undid my contributions (except Möbius plane) in order to restore the images. The Möbius plane version of my sandbox I made more smooth with less verbatim and less mathematics. Please have a look. I would prefer my version, because a reader can easier recognize the commons and the differences of the three geometries (Möbius-, Laguerre-, Minkowski-plane). Ag2gaeh (talk) 14:05, 23 March 2013 (UTC)
 * I'm a bit short of time right now, but I can give you a very quick impression. There are a lot of symbols that can be replaced by natural language - for example, the logical symbols. Also, the lemmas don't really need to be identified as such. And it would really help if you provided more context. Imagine you're writing for American Mathematical Monthly or the Mathematical Intelligencer. RockMagnetist (talk) 16:42, 25 March 2013 (UTC)

List of circle topics
I've added Bundle theorem and Benz plane to the List of circle topics. If you know of others that are not there and should be, could you add those too? Michael Hardy (talk) 19:21, 22 January 2014 (UTC)


 * Thank You for the hint to this great list. It may be hard to find a statement not on this list.--Ag2gaeh (talk) 08:53, 23 January 2014 (UTC)

Disambiguation link notification for April 2
Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Implicit curve, you added a link pointing to the disambiguation page Normal. Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ* Join us at the DPL WikiProject.

About Steiner conic
Hi, and thank you for your contributions to Wikipedia. It appears that you tried to give Steiner conic a different title by copying its content and pasting either the same content, or an edited version of it, into another page with a different name. This is known as a "cut-and-paste move", and it is undesirable because it splits the page history, which is legally required for attribution. Instead, the software used by Wikipedia has a feature that allows pages to be moved to a new title together with their edit history.

In most cases, once your account is four days old and has ten edits, you should be able to move an article yourself using the "Move" tab at the top of the page (the tab may be hidden in a dropdown menu for you). This both preserves the page history intact and automatically creates a redirect from the old title to the new. If you cannot perform a particular page move yourself this way (e.g. because a page already exists at the target title), please follow the instructions at requested moves to have it moved by someone else. Also, if there are any other pages that you moved by copying and pasting, even if it was a long time ago, please list them at Cut-and-paste-move repair holding pen. Thank you.

Which software did you use to create File:Quadriken-7.svg? I am looking for 3D software that exports SVG. Thanks. SharkD  Talk  20:36, 25 November 2015 (UTC)


 * I am using software written by my own in PASCAL (freepascal). It generates EPS-files, which I transform into SVG-files. --Ag2gaeh (talk) 21:29, 25 November 2015 (UTC)

ovals
As you've probably noticed, I've been incrementally modifying your edits on the oval page and there are two things I'd like to bring to your attention. First, you might wonder why I have been changing notation. I have found, over the years, that English readers are not very fond of the Fraktur font and much prefer Greek or Latin versions. Many Germans in the US (but not all) have noticed this and have moved away from using Fraktur in their classes and notes. I personally have no problem with this font, but I felt that I should make the change in accordance with this viewpoint. My second point is a question. In several of these pages you have made the comment that in infinite planes ovals always exist. Surely there must be some restriction here. I know of no general construction that will always give an oval, and I don't see how you could prove something like that in a free plane. If I am missing something, please let me know. Thanks. Bill Cherowitzo (talk) 17:17, 15 March 2016 (UTC)
 * Thank You for Your effort. Yes, I think, it is a good idea, to use more common notations. To ovoids in infinite spaces: It should be theorem 3.4 in a paper of HEISE ( W. Heise: Bericht über $$\kappa$$-affine Geometrien, Journ. of Geometry 1 (1971), S. 197–224, Satz 3.4.) and, so far I know, there is no further restriction. But it is not a constructive method. Only existence is proven. --Ag2gaeh (talk) 22:11, 15 March 2016 (UTC)

Disambiguation link notification for February 23
Hi. Thank you for your recent edits. An automated process has detected that when you recently edited Evolute, you added a link pointing to the disambiguation page Deltoid ([//dispenser.info.tm/~dispenser/cgi-bin/dablinks.py/Evolute check to confirm] | [//dispenser.info.tm/~dispenser/cgi-bin/dab_solver.py/Evolute?client=notify fix with Dab solver]).

Translation suface (differential geometry)
Hello.

Please note that the capitalization of the "d" in "Translation surface (Differential geometry)" is incorrect under WP:MOS. I have changed the title to Translation surface (differential geometry). Michael Hardy (talk) 19:28, 30 November 2018 (UTC)
