Math olympiad handouts

I have been teaching math olympiad teams since high school. A single lecture (or more, an interactive problem-solving session) is usually over 3 hours long, and covers a topic + a list of difficult math problems on the topic.

The class size is usually between 6 and 12. The target audience are high school students preparing for the International Mathematical Olympiad (IMO) and easier competitions of the same type. Most of my handouts are not translated (and many not polished enough for publication); but I consider the following to be quite good.

• The power of the handshaking lemma
• Algorithms and posets

The LaTeX template is adapted from Evan Chen. In my olympiad days, I’ve found the websites of Yufei Zhao and Alexander Remorov to be quite useful.
