I provide the source for most of my notes. The hope is that somebody will download all my notes, correct the errors and unclear presentation, and then send them back to me. It's not likely, but it could happen. Alternatively, if a bomb drops on my house and I lose all my stuff, maybe somebody can give me a copy of my notes.

My notes (pdf, tgz), made from Tony's notes, of Yonathan's prelim workshop on analysis.

One of my favorite facts about right adjoint functors is that they commute with limits.

Sestina's and primes, an easy problem Richard and I worked out our first year, which I wrote up for some reason.
