I occasionally write expository notes mainly to facilitate my own understanding. I put them here in case somebody else finds them useful. Note that some of these are in an unfinished state.
- An analysis of a spectral-partitioning-type theorem from this paper
- A useful theorem about random walks from this paper
- An exposition of Mihail's combinatorial analysis of graph expansion
- Tolerant testers for self-correctable properties
