- The Derived Category of the Intersection of Four Quadrics
  Preprint, arXiv:0904.1764
- Spinor Sheaves on Singular Quadrics
  Preprint, arXiv:0904.1766
- A Method for Recovering Arbitrary Graphs
  My undergraduate thesis, based on my work in Jim Morrow’s REU at the University of Washington.
  Here is the C++ program mentioned in the paper.
Notes
- Fiber Bundles and Non-Abelian Cohomology
  Talk given at the 2007 Graduate Student Topology Conference.
- Notes on Spin and Pin
  A hodge-podge of facts centered around getting characteristic classes from short exact sequences of Lie groups.
  Also, the “accidental isomorphisms” Spin(3) = Sp(1), Spin(4) = Sp(1) × Sp(1), Spin(5) = Sp(2), and Spin(6) = SU(4) given explicitly.
- Algebraic Geometry of the Ring C(X)
  If X is compact, the maximal ideals of C(X) correspond to points of X. What about the prime ideals?
- hodge.cpp
  A C++ program to compute the Hodge diamond of a complete intersection in Pⁿ. I guess this doesn’t quite belong under Notes.
Teaching
Miscellaneous
- Croquet in Ann Arbor
- Sheepshead reference sheet. Shamelessly xeroxed from the back of Bob Strupp’s book, which you should buy.
