A gratuitous bit of self publicity, but at www.maths.bris.ac.uk/~maxmg/maths[/URL] are some bits of maths people may find interesting. There are, if you look around, articles on representation theory, some introductory notes to groups, exercises of many kinds, some research notes if you look hard enough (try [PLAIN]www.maths.bris.ac.uk/~maxmg/research.html[/URL]), links to all of Grothendieck's published work. If there's anything anyone wants to add then please let me know. I'd be keen to collect lots of (hard!) exercises for people to use for whatever purpose they see fit - look at the pdf of exercises to see what kind of level of difficulty we're talking about. I'd also be keen to have anyone's contributions of a similar nature. Want to explain 3 different proofs of the fundamental theorem of algebra, feel free to write one. The aim is not encyclopedic but interesting. I may for instance write something about why Dynkin Diagrams are so pervasive in algebra, something understandable to someone who knows what a graph (vertex/edge sort) is and what a positive definite inner product is.
