[edit] Photos, P:RUS

Maybe you can release your own photo (and photos of some other modern mathematicians) with a GFDL or other free copyright?

[edit] Igor Pak article at AfD

An article that you have been involved in editing, Igor Pak, has been listed at Wikipedia:Articles for deletion/Igor Pak. Please look there to see why this is, if you are interested in whether it should be deleted. Thank you. --Eastmain 20:54, 3 January 2007 (UTC)

[edit] 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.

[edit] "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.

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)

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).

...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.

[edit] Algebraic combinatorics

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