Here is information are my various research papers, lecture handouts, textbooks, and so on.
My two largest projects at the moment are

Here are lecture notes for lectures, sessions, etc. that I have given, generally to high school students. These are in general easier than my Olympiad handouts. They also tend to leave out lots of details (after all, the handout usually accompanies a two-hour talk).
To compile these documents in LaTeX, you will need evan.sty.
