Here's how it works:
  1. Anybody can ask a question
  2. Anybody can answer
  3. The best answers are voted up and rise to the top

First, my apology for this soft question. My excuse was that I really think this may be of interest to the community. I would understand if it gets closed (I have advocated closing some soft questions myself, so it's fair).

Background/Motivation: Recently at an AMS meeting I decided to attend a special session outside my interests and had a lot of fun. Also, to learn about what is going on in a different but related area, I found it very useful to look at some recent conferences and start by skimming the list of speakers and abstracts/notes. So a website with recent and upcoming conferences would be useful. They are not always easy to find with Google.

Requirements: Since this is soft, let's take some care to make sure it will not be too easy to answer. So let's define "specialized community" to be "there is at least one AMS special session devoted to (part of) it. Also, the more useful the website is the better (for example, one should preferably contains list of conferences, and perhaps more)

Examples: here is one I visit frequently: for commutative algebra

Another one I found recently and like a lot: Finite dimensional algebras

Surely there must be others?

Close it? No way -- this has got to be one of the most useful soft questions we have yet had on this site. – Pete L. Clark Feb 10 '11 at 5:03
May I suggest that this is one of those questions where there should be just one answer which everyone adds their sites to (those without enough rep can leave comments/answers to be added and then deleted). That way, the list can be organised more usefully than by "votes" or dates. – Loop Space Feb 10 '11 at 7:44
@Andrew: that is a good idea, but unfortunately now it is a bit late to do that. Perhaps after a while I can make an answer compiling all the links? – Hailong Dao Feb 10 '11 at 21:03
I dunno; isn't it pretty easy to just skim down the page and click the links that interest you? Am I missing something, Andrew? – Tom Leinster Feb 11 '11 at 12:10

Open source mathematics software -- we've had a lot of talks about Sage in special sessions, and next year in Boston we'll have an AMS minicourse on Sage.

This one looks super-cool, thank you. – Hailong Dao Feb 11 '11 at 14:37

Arg, how could I forget the nLab?? – David Roberts Feb 10 '11 at 1:57

Here comes some sites that list upcoming (and also previous) conferences in the field of operator algebras

One maintained by Paulo Pinto:

Another maintained by Michael Anshelevich:

And a third maintained by Narutaka Ozawa:

Operator algebra page of N. C. Phillips:

Not sure if these have special sessions, but they are pretty broad:

@David: excellent, thanks! Broad is OK, by my definition. – Hailong Dao Feb 10 '11 at 0:04

This is very nice, thanks! – Hailong Dao Feb 10 '11 at 1:58

Dear Pete, thanks! I especially like the Galois Theory page, but it looks like the site has not been updated for a while. Do you know if there is a newer site, surely the community still exist? – Hailong Dao Feb 10 '11 at 21:07
@Hailong: unfortunately I do not know of a newer / more active site. – Pete L. Clark Feb 10 '11 at 22:07

As far as logic goes, there is the Association of Symbolic Logic website. It has a very comprehensive list of logic meetings, which includes the ASL meetings, the officially sponsored meetings, and more.

Sarah Whitehouse keeps a list of meetings in algebraic topology and related areas.

A few more for Logic:

Mathematical Logic Around the World contains a lot of useful information about Logic departments, Logic journals, LaTeX for Logicians etc. The events section is a little outdated though.

The European Set Theory Society has conference announcements as well as slides from the conferences.

There is also the Young Set Theory Network, which has conference announcements, and hopefully will have more things in the future.

Affine algebraic geometry.

Cluster Algebra Portal.

how many of those tiddlyspot websites are there for math? how hard are they to make? – Sean Tilson Feb 15 '11 at 3:07
Sean, the homotopy one is the only one I know. – Hailong Dao Feb 15 '11 at 18:03
