Here are some of the course notes I've taken over the years. But first, a few remarks:

• Some rows can be expanded to see other relevant documents (syllabi, problem sets, etc.)
• If the updated date is green, I am currently working on updating those notes.
• Notes from before the summer of 2012 are scanned, so they'll take a bit longer to download.

• Preliminary syllabus
• Professor Nori's notes (includes homework assignments)

• Syllabus
• Homework assignments
• Jordan Ellenberg wrote about my notes!

• Homework assignments
• Old notes from a probability course taught by Professor Lawler

• Syllabus
• Homework assignments
• Professor Farb's course notes
• Some motivating questions in algebraic topology
• McCleary - A History of Algebraic Topology
• Stillwell - translation of Poincare's Analysis Situs

• Syllabus
• Background test
• Homework assignments

Stuff from PROMYS:

• Playing fast and loose with geometric series
• Counting colorings cleverly
• Category theory
• An introduction to differential topology
• Vector bundles
  There is an error about parallelizable manifolds on page 5 of these notes; see this math.SE thread. This originates from an error on page 115 in the 1st edition of Lee's Smooth Manifolds; see the errata for the book.
• Point-set topology

Miscellaneous:

• My final project for complex analysis. I was kind of rushed towards the end, there's a lot that I'd like to add sometime.
• A proof that sheaves can be glued (Hartshorne, Exercise 2.1.22). I wanted to get every last detail…
• I wrote up a brief introduction to higher ramification groups as my final project in one of my graduate number theory courses at Brown.
• For the final exam in one of my undergraduate real analysis courses, we were allowed to take exactly one sheet of notes with us. This is what I brought.
• Here is my write-up for a fun little open-ended project on happy numbers, from my undergraduate number theory course.
