Exposition

Occasionally when people teach me things, I write them down. This is done neither as frequently, nor as accurately as I'd like, but might prove useful every now and then to someone nonetheless.
  1. Toroidal and Log Structures. A very quick and dirty introduction to thinking about toroidal embeddings and log structures. 
  2. The Tangent-Obstruction Complex. My notes from trying to learn about obstruction theory in the context of GW invariants. 
  3. 2875 Lines on the Quintic Threefold. A sketch of this classical result from enumerative geometry.
  4. Grothendieck Ring of Varieties. My notes from a lecture by Ravi Vakil at WAGS.
  5. (Tropical) Hilbert's Theorem 90.
