Here are some things that aren’t big enough to warrant individual posts. Well, just two things.
First up, I’ve recently become aware of the Open Problem Garden which seems to have the laudible purpose of putting together a database of open problems and conjectures in math and theoretical computer science. It’s pretty much dominated by graph theory stuff at the moment, though. Anyone got a good pile of topology, geometry, algebra and analysis problems to put in? If it’s to be worth anything as a resource, it does need the support of the community.
And second, on the 11th, I’m hosting the Carnival of Mathematics (in theory…don’t know what I’m doing, haven’t hosted a carnival before). So, please submit stuff to it. I know that some people consider it a carnival of lower mathematics, and I’ve looked over the last few and tend to agree. I’m still quite happy to host it, though. Now, if people want a more research level mathematics carnival, I’m also willing to start and organize a Carnival of Higher Mathematics, so if you’d be willing to contribute semi-regularly to something of that sort, please leave a comment.
