This page contains notes I typed in classes I’ve taken. Currently, I live-TeX notes using latexmk and a heavily modified Vim editor. (For details on the technical setup, see the corresponding FAQ.) Since these notes are written during class, it is quite likely that they contain typos. Please send any corrections to me via email.

For more polished exposition on some selected topics, see the Napkin project.

Here is a download link for descriptions of courses I took, even including the ones which I do not have notes for. (The list below just includes the one for which I have notes to share.)

Massachusetts Institute of Technology#

• (18.02) Multivariable calculus (pdf, work-in-progress) (github)
  Here I was a recitation leader rather than a student, so this one actually looks more like a book. If you’re actually in my section, you should check the class page instead.

• (18.217) Combinatorial Theory (pdf, incomplete)
  Taught by Alex Postnikov. Fall 2018.

• (18.218) Topics in Combinatorics (pdf)
  Taught by Alex Postnikov. Spring 2017.

• (18.435) Quantum Computation (pdf)
  Taught by Seth Lloyd. Fall 2015.

• (18.757) Representations of Lie Algebras (pdf)
  Taught by Laura Rider. Spring 2016.

• (18.786) Number Theory II (pdf, incomplete)
  Taught by Andrew Sutherland. Spring 2018. These notes are very far from complete.

• (18.950) Differential Geometry (pdf)
  Taught by Xin Zhou. Fall 2015.

• (SCUM) Student Colloquium in Mathematics (pdf)
  Not a class, but free dinner and math lectures every Wednesday.
