Sorry for asking something that's not really related to Wikipedia, but here goes. I recently put on line a paper I wrote commenting on the attempt of Louis de Branges de Bourcia to prove the Riemann Hypothesis. How can I bring it to the attention of those who would be interested?

I'm currently attending this workshop which is charged with producing a white paper on how to make (or the prospects for making) progress towards a library of mathematics suited to today's digital world. As there are already a number of candidate languages in current use there are questions of who such a GDML is for, how compatible or intertranslatable the extent candidates are, whether the initial focus should be at the level of vocabulary, syntax, ambiguity (in either vocabulary or syntax), functions, concepts, or semantics, and like questions.
Are there members of WikiProject Mathematics who feel they could usefully represent the wikiproject's (or more generally Wikipedia's) attitudes towards, and opinions about, GDML's goals, prospects, methodology, etc.? Vaughan Pratt ( talk) 20:36, 5 February 2016 (UTC)
Hello there. Recently I am reading matrix calculus and there is one scalar-by-matrix identity that I could not understand.
According to my understanding and nominator layout, it should be while the wiki page suggests that it should be instead. There is no such identity in the matrix cookbook (perhaps we can replace the matrix A with I in derivative #124?), so I seek your advice. Estorva ( talk) 14:04, 5 February 2016 (UTC)
@Estirva and @Tsirel: You deficiency of TeX skills is showing. Here's a comment I just left on the talk page of the article discussed here:
When one writes {\rm tr} in TeX one does not get proper spacing before and after "tr". Thus
- is coded as a {\rm tr} B, and
- is coded as a \operatorname{tr} B, and
- is coded as a \operatorname{tr} (B).
Writing \operatorname{tr} results in a certain amount of space before and after tr, and there is less space when (round brackets) follow tr than when they don't. The form {\rm tr}, on the other hand, involves no spacing conventions. The form \operatorname{tr} is standard usage and I edited accordingly.
The same thing applies to \text{tr}, which both of you used here. Michael Hardy ( talk) 21:31, 7 February 2016 (UTC)
Both variants,
(from propagator and history) are bad. In the first, the prime is misplaced. In the second, the dagger fails to penetrate its victim and there is an ugly gap between the i and the del operator. Does anyone know of a workaround (or even a supported feature)? YohanN7 ( talk) 10:05, 4 February 2016 (UTC)

I'm wondering if Spacetime triangle diagram technique should be moved either to Spacetime triangle diagram or to Spacetime triangle? (I found the article full of crude solecisms, some of which I cleaned up, and bizarrely over-complicated TeX code written by a psychotic (which probably means it was written by some software package of the kind used by people who don't know TeX code) and I cleaned up some of that too.) Ceteris paribus, I think shorter titles are better, partly because they're more likely to be found by using the search box. Michael Hardy ( talk) 19:58, 16 February 2016 (UTC)
The user, Ryanexler is planting a reference in various articles. He/she (most likely to be Jakob Schwichtenberg ) has done this once before (last year) and was then reverted by me. I don't feel like being this mans nemesis around here. Someone else should have a look. YohanN7 ( talk) 12:30, 12 February 2016 (UTC)

This proposed change in the title of an article might perhaps benefit from insights of participants in this page. Michael Hardy ( talk) 20:21, 16 February 2016 (UTC)
We have a new article titled Georg Cantor's first set theory article, written largely by an expert on the history of the matter, R. J. Gray, who has published refereed papers on the topic.
I have added a "mergefrom" tag to it, which may be controversial. There is a large overlap between the two articles. The rationale for creating a separate article with a separate title is explained by R. J. Gray in this section of my user talk page.
Currently no other articles link to this new article. So that's something to work on. Michael Hardy ( talk) 03:27, 13 February 2016 (UTC)
The article Effect algebra was copied from http://arxiv.org/pdf/1602.00567v1.pdf, making it a copyright violation. GeoffreyT2000 ( talk) 01:49, 17 February 2016 (UTC)
I've done some editing on this article. If it was a copyright violation earlier, it probably is not now. It didn't have a proper introductory sentence; I've added that. Michael Hardy ( talk) 18:48, 17 February 2016 (UTC)
Recap: I am blind and a newbie, but an expert on the Jacobian Conjecture(JC). Around January 20, I proposed a change to the JC article on the talk JC page, under the title Symmetric Case. I pointed to it here, but the pointer was archived with no action. Needs a reference to two papers by the same two authors in the same year. Please help.

I have created the System U article and would appreciate if somebody checked its wikiness. Also, looking at related articles, I noticed they have this WikiProject's rating template on their talk pages. I don't know what the process around these is, but this article should probably have one as well. — Matěj Grabovský ( talk) 12:37, 19 February 2016 (UTC)
I'd like to get P-value fallacy in WP:DYK. ( User:Sunrise gets all the credit, not me.) It'd be nice to have a decent mathematics article on the Main Page. I'd appreciate it if a few stats people looked it over and/or suggested a good "hook" for it. Realistically speaking, we probably can't expect to find very many stats people among the DYK reviewers, so I'm asking here. If anyone has comments, please be bold, or leave notes on the article's talk page. WhatamIdoing ( talk) 01:56, 22 February 2016 (UTC)
In this section I found only two sieve methods listed, not including the sieve of Eratosthenes about which everyone learns in elementary school, and which is in fact the only one that I know anything about. I added several more. Quite possibly the section needs more work. Maybe even subsections on different kinds of sieves? Or maybe not? Michael Hardy ( talk) 18:43, 25 February 2016 (UTC)
Some of you may be interested in this:
There is a Tech Talk next Monday, 29 February at 20:00 UTC (12 Noon Pacific Time) about Zotero and the mw:citoid service.
The main subject is how to extract accurate, automated bibliographic citations from websites. This talk is mostly about Zotero, which is a free and open-source citation management tool. Zotero is used on the Wikipedias through the automagic citoid service. Citoid is currently an option in the visual editor and will (eventually) be used for automated citations in the wikitext editor at some Wikipedias. Zotero is also used by many academics and researchers, and most of the information presented will be useful to people outside of Wikipedia as well.
Please share this invitation with anyone that you believe will be interested. If you have questions, then please leave a note on my talk page. Whatamidoing (WMF) ( talk) 03:43, 24 February 2016 (UTC)

00:38, 27 February 2016 (UTC)Our list of new articles at User:Mathbot/Changes_to_mathlists includes a new article titled Modified KdV–Burgers equation. It was a total orphan, so I created one link to it in the "See also" section of the article titled Korteweg–de Vries equation. Then I decided to add it to the List of dynamical systems and differential equations topics, and I found that even " Korteweg–de Vries equation" is not listed there, and it's not immediately clear where within that list it would belong. Should the list itself get reorganized? Michael Hardy ( talk) 00:51, 29 February 2016 (UTC)
