Coupon collector's problem

I've just done the sorts of minor style edits that I do by reflex; next I'll look at actual content. In expressions like this:

i-1

there are three things that conflict with style conventions at Wikipedia:Manual of Style (mathematics). All three are intended to make non-TeX mathematical notation similar to TeX in style conventions.

(1) Digits and punctuation should not be italicized; variables should. Thus f(x) is right; f(x) is not.

(2) A full-fledged minus sign is longer than a stubby little hyphen.

(3) Spaces should preceed and follow the minus sign. I used the "non-breakable space character" so that no line-breaks could interrupt the expression i − 1 as the user alters the window size on the browser.

Here's what it looks like after those edits:

i − 1

In TeX, I changed

a+\ldots +z\,

to

a+\cdots +z\,

I don't think this one is a universally agreed on. In fact there is disagreement about whether to use inline (as opposed to "displayed") TeX. On many browsers it looks much bigger than the surrounding texts or fails to get aligned well with the surrounding text.

"content"

The first thing that comes to mind besides the main ideas of the article is whether you've linked to everything that should get linked to, and there I don't immediately see any obvious definciencies. The next question related to that is whether this article is linked to from the various other articles that should link to it. You can never be sure of this, but you could start by considering which section of the list of probability topics should link to this page, and then go down that list to see which other articles listed there should link to this one. Michael Hardy (talk) 21:38, 15 December 2007 (UTC)[reply]

So you see, I'm taking these in this order: those edits that can be done in a few seconds (now done); those that take a several minutes (not all done); those that take leisurely pondering.... So I'll be back. Michael Hardy (talk) 21:40, 15 December 2007 (UTC)[reply]

Notice that if you click on "what links here" you'll find all articles, project pages, and talk pages that link to the article. Here's the whole list:

User talk:Igorpak (links)
Wikipedia:Missing science topics/Maths6 (links)
User talk:Michael Hardy (links)

This qualifies the article as what is called an "orphan". Putting the "probability theory" category tag on the article (or any of dozens of various other math category tags) will automatically cause the article to get listed at list of mathematics articles within a couple of days or so. And also at Wikipedia:WikiProject Mathematics/Current activity in the "new articles" list, so then those who regularly look at that list may be moved to do some of these edits (either on the article itself or on the various others that should link to it). Michael Hardy (talk) 22:14, 15 December 2007 (UTC)[reply]

...OK, you'll notice that among those pages now linking to this article is a redirect page, Coupon Collector's Problem. That is an incorrect capitalization (by Wikipedia's conventions), and there may also be commonplace misspellings, misnomers, and alternative names for the same thing, and if you can think of any of those it is a good idea to create a redirect page for each of them. That way anyone linking to any of those alternative names in another article or entering it into the "search" box will find the existing article. Otherwise, they may concluded none exists and create the srticle under an alternative name, and then you and whoever works on that other article will be unaware of each other's existence, initially. When the existence of both articles gets noticed, then a decision would need to get made about which, if either, title the two should get merged into. Also, one sometimes finds that as soon as you create such a redirect page and then click on "what links here", a hundred other articles already link to that alternative title.

Algebraic combinatorics

Algebraic combinatorics is a new article. Maybe you can help civilize it? Michael Hardy (talk) 03:47, 24 December 2007 (UTC)[reply]

Cardinality-based notation for sets

I've just gotten around to taking your advice (15 February on my talk page) and created an article on set notation. I'd be curious what you think of it. Regards—PaulTanenbaum (talk) 16:14, 30 August 2008 (UTC)[reply]

Jim Whittaker?

Jim Whittaker is a mountain climber. Is he related to the James V. Whittaker who worked on the mountain climbing problem? Michael Hardy (talk) 04:46, 8 December 2008 (UTC)[reply]

....Oh, I see: he's James W. Whittaker. Michael Hardy (talk) 04:47, 8 December 2008 (UTC)[reply]

Levy and Gromov

Privet Igor, As per your edit at isoperimetric inequality, I think it's a little odd to describe Levy's inequality in detail and not mention Gromov's paper which seems to be the main source for this area. Katzmik (talk) 09:05, 23 December 2008 (UTC)[reply]

Yes, sure. I think it was never published, but eventually incorporated into one of his book. Of course, both Gromov and Levy's work is much more general than this simple spherical inequality, but if you do have a reference it might be a good idea to add it. The reason I added this inequality is because it seemed nice simple and elegant, way more relevant to average Wikipedia reader than advanced generalizations. Igorpak (talk) 09:34, 23 December 2008 (UTC)[reply]

At any rate it's an IHES preprint. Katzmik (talk) 10:13, 23 December 2008 (UTC)[reply]

Did You Know problem

Hello! Your submission of Discrete Mathematics (journal) at the Did You Know nominations page has been reviewed, and there still are some issues that may need to be clarified. Please review the comment(s) underneath your nomination's entry and respond there as soon as possible. Thank you for contributing to Did You Know! Art LaPella (talk) 21:48, 15 March 2009 (UTC)[reply]

As my link and it's sublink Wikipedia:Did you know/Prosesizebytes explain, you can see what our script counts and what it doesn't by going to the Discrete Mathematics (journal) article, and entering this into your browser's URL field: javascript:importScript('User:Dr pda/prosesizebytes.js'); getDocumentSize();

It only counts your introduction and your Discrete Mathematics (journal)#History section. The material our software doesn't count is interesting/useful, but in my experience you won't have much luck arguing for such an exception. Anyway, I won't be the one to make such a decision; I do routine proofreading. The surest way to overcome this objection is to add at least 349 bytes of prose (not list entries or references etc.) to your article. Art LaPella (talk) 22:02, 15 March 2009 (UTC)[reply]

It's long enough. Thank you. Once again, others do approvals. Art LaPella (talk) 03:35, 16 March 2009 (UTC)[reply]

DYK for Discrete Mathematics (journal)

On March 22, 2009, Did you know? was updated with a fact from the article Discrete Mathematics (journal), which you created or substantially expanded. If you know of another interesting fact from a recently created article, then please suggest it on the Did you know? talk page.

Looking for Wikipedia Ambassadors

Hi! I'm leaving you this message because you are listed as a Wikipedian associated with Harvard. The Wikipedia Ambassador Program is currently looking for Campus Ambassadors to help with Wikipedia assignments at schools in Boston and Cambridge (including Harvard), which will be participating in the Public Policy Initiative for the Spring 2011 semester. The role of Campus Ambassadors will be to provide face-to-face training and support for students on Wikipedia-related skills (how to edit articles, how to add references, etc.). This includes doing in-class presentations, running workshops and labs, possibly holding office hours, and in general providing in-person mentorship for students.

Prior Wikipedia skills are not required for the role, as training will be provided for all Campus Ambassadors (although, of course, being an experienced editor is a plus).

If you live near Boston and you are interested in being a Wikipedia Campus Ambassador, or know someone else from the area who might be, please email me or leave a message on my talk page.

If you're an experienced and active Wikipedian, you might be interested alternatively in becoming an Online Ambassador. The role of Online Ambassadors is to serve as mentors for students; it doesn't require any in-person outreach. Take a look at the Online Ambassador guidelines; the "mentorship process" describes roughly what will be expected of mentors in the coming term. If that's something you want to do, please apply!

You can find instructions for applying at WP:ONLINE. The main things we're looking for in Online Ambassadors are friendliness, regular activity (since mentorship is a commitment that spans several months), and the ability to give detailed, substantive feedback on articles (both short new articles, and longer, more mature ones).

"Euclidean algorithm"

Hi - thank you for your edits :) . The story of the Euclidean algorithm is a bit more complicated; I've just made a quick edit to the "computations in number theory" section - tell me what you think. Garald (talk) 09:44, 11 October 2011 (UTC)[reply]

Computations section

Hi - It seems we have to add references to "Recent approaches and subfields" on short notice (we are being rated whether or not we feel ready - I swear I didn't ask for this!). Can you take care of the "computations in number theory" subsection? Make further changes if you believe they are necessary. Garald (talk) 10:00, 8 November 2011 (UTC)[reply]

Baxter permutation

Thanks for creating Baxter permutation. That's been on my to-do list for a while, but now I can cross it off. —David Eppstein (talk) 05:33, 28 November 2012 (UTC)[reply]

Sergey Kislitsyn moved to draftspace

An article you recently created, Sergey Kislitsyn, 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 "Draft:" 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.

Hi Igor. I have undone this horrifically-bad example of making Wikipedia hostile by User:WaddlesJP13. Its description of your article is incorrect, the article was perfectly suitable as written, and it should not have been draftified. —David Eppstein (talk) 06:52, 21 October 2022 (UTC)[reply]
