Kaisa Group Holdings Limited moved to draftspace
An article you recently created, Kaisa Group Holdings Limited, is not suitable 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.

Two new articles about researchers on topological vector spaces; research sections could use expansion
Hi — I think you are particularly interested in topics here related to topological vector spaces. I recently created two articles on researchers in this area, Susanne Dierolf and Nicole De Grande-De Kimpe, where I think your expertise could be helpful in expanding the research sections. Both have sources listed already that go into considerable detail about their research, but in their articles I summarized this material only in the broadest of terms because I did not feel comfortable enough with the material to write more. In both cases, a section on their research contributions of comparable length to the other biographical sections would probably be an improvement. If you're not interested, that's ok too, but I just thought I would bring it to your attention as a topic you might be interested in improving. —David Eppstein (talk) 22:06, 4 December 2021 (UTC)

General usage for piped links
Hi,. I noticed that when you do massive edits of a given page, you often replace wikilinks in piped form with a form with a fully spelled out target and don't want to seem to use Help:Pipe_trick. For example, you use  when the simpler   could be used. The "pipe trick" is really convenient, shortens the source and makes it easier to read and edit. Would it be possible for you not to remove previous "pipe trick" links in the future?

Also note that wikilinks are case sensitive, except for the first letter (see Help:Link). So  and   would both link to the same page, and display as capitalized or not capitalized respectively. Best regards. PatrickR2 (talk) 04:37, 18 May 2022 (UTC)
 * Okay. Thank you for the explanation. Mgkrupa  05:04, 18 May 2022 (UTC)

Tensors and Manifolds navigation boxes
Hi, Mgkrupa. I see you've been editing the tensors and Manifolds nav boxes recently. I noticed on the article One-form that there is a weird spurious space occurring between them. Any idea why? Jason Quinn (talk) 14:37, 30 June 2022 (UTC)

Rename Template:Order theory?
Hi! Thanks again for create the template. I'd like to suggest to generalize its name (or at least its main heading) to reflect its more general contents: "Properties & Types" and "Constructions" seem to apply to relations in general, not just orders. "Symmetric closure" doesn't even yield any kind of order (except for trivial reflexive preorders). - I'd suggest to call the template "Binary relations", but Template:Binary relations already exists. Maybe the latter should be renamed more appropriately? - Jochen Burghardt (talk) 13:20, 16 December 2022 (UTC)
 * Hi Jochen. You can change the title of the template or you can get rid of links like "Symmetric closure" to make the list fit the template name. When I was adding items to the template, I might have added some things that shouldn't be there (or that I intended to remove but forget about) so feel free to remove those. If you want to change the title, then I recommend changing the "name = " and "title = " instead of moving/renaming the template.
 * And FYI The reason I included links to thinks like "Equivalence relation" is because they are sometimes relevant to order theory. For example, you can often build preorders from certain binary operators (that are not pre-orders) by using closure operators and related things. For example, any strict total order on a partition of a set X induces a strict weak ordering on X but going the other way involves equivalence relations (to define the partition). But again, feel free to remove things you feel are inappropriate because when I created it, I fully intended for other people to improve it. Mgkrupa  22:34, 16 December 2022 (UTC)

About Stephen Willard
Hi Mgkrupa. Please take a look at the history of this template: https://en.wikipedia.org/w/index.php?title=Template:Willard_General_Topology&action=history. In Oct 2021 and then Sep 2022 I removed the author-link field, because Stephen Willard does not  refer to the topologist, but instead refers to another person, namely a professional darts player. Every time you reverted that back. Would you mind removing the author-link yourself this time? Thanks in advance! PatrickR2 (talk) 17:16, 3 March 2023 (UTC)


 * I didn't notice. Thanks for pointing that out. Mgkrupa  02:28, 6 March 2023 (UTC)
 * I have removed the three author-links in the template, as there is practically no public information about Stephen Willard, hence preferable not to have these red links. Regards. PatrickR2 (talk) 01:26, 21 March 2023 (UTC)

Request for Norm topology
I notice that you have written some huge pages on assorted operator topologies, and so I would like to make a request. The page norm topology is current a redirect to operator norm, which never actually talks about topology. The norm topology appears in the lede for C*-algebra, which is a high-importance article for both math and physics. And so here's the problem: its late at night, I'm tired, and I have a vague recollection that C*-algebras are defined with weak topologies (cause that's what Hilbert spaces conventionally use). And yet, norm topologies, as I recall, are usually strong topologies, and so I can't really tell which was the intended use, here. I figure that you would know enough to be able to disambiguate what this link should have been.

I have a second request, to go with the first: I notice that your polar topology and strong topology articles are long, dense, and packed with details. I note that the C*-algebras article, being high-rated and important to physics, is going to attract a lot of readers who have only the most minimal, rudimentary comprehension of norms and topologies and dual spaces. And thus, however norm topology is redirected or re-written, it should go to some article that would be accessible to ... physics students. Do you think you can fix all this up?

... and just as I was about to hit "save". I discovered Operator topologies. Which places norm topology at the top of the heap. Which is that damned redirect. Sigh. 67.198.37.16 (talk) 07:54, 26 November 2023 (UTC)


 * ... and just now, I actually read Operator topologies and I would be quite content if norm topology just redirected to the Intro section of that article. That's mostly enough to serve my needs (it being late at night and all.) 67.198.37.16 (talk) 08:10, 26 November 2023 (UTC)

Your edit for injective tensor product
Hi – in this edit to the article on the injective tensor product, you replaced X* by $$X^{\prime}$$, resulting in "We will denote the continuous dual space of $$X$$ by $$X^{\prime}$$ or $$X^{\prime}$$". Since you also changed asterisks to primes in other parts of the article in that edit, I suspect that you intended to just get rid of the asterisk notation. Since the article no longer uses that notation, I've changed it to just say "We will denote the continuous dual space of $$X$$ by $$X^{\prime}$$"; I just wanted to check that that's what you had in mind.
