If you’re interested in recent developments in abstract algebra, an excellent place to look is the homepage of William Crawley-Boevey. He provides lecture notes covering quivers (which we’ve discussed before), the cohomological approach to central simple algebras, and invariant theory.

Apologies for this comment which isn’t relevant to this post, but I wasn’t sure where else to put it. Please delete/put somewhere else if you wish.

I would like to use the feed from this blog but the best I can get from eg http://www.arsmathematica.net/feed/ is a blank page. I have tried other things that usually work with WordPress but to no avail. Any help would be much appreciated!

It’s probably a problem on our end — the RSS feed for comments is working fine. We’ll investigate.

I upgraded WordPress. This should fix the problem.
