Resources

This is an assortment of materials I found useful for study, or stuff I made.

1. Problems in Life, sets 1 and 2 - These are some problem sets I made, associated to my talks (first one on Monsky's Theorem, second one on Minkowski's and Pick's Theorem; see talks) at INMO Training Camp 2018. 

2. Problem sets on Billiards and Adding Figures, associated to my two talks at INMO Training Camp 2019.

3. Dianthe Basak, Neha Rino and I translated this paper by H. Akrout, titled Topological Singularities of Generalized Systoles.

4. At one point of time I was into making Olympiad problems. Here is a fun combinatorics problem and here is a fun geometry problem I made.

5. Here are some notes for a course (in Spring 2017)  on Probablity by BV Rao, these are pretty good. 

6. Rules for BattleFish - A version of Canadian Fish (the card game) made by Dianthe Basak and myself, for those who find the original game far too easy.

Links I found useful - 

• John McCammond's page on Geometric Group Theory - This contains a comprehensive list of people and organisations associated with geometric group theory, as well as recent news on the subject.

• Software SnapPy  is great for studying properties of knots and links.

• The PROMYS Reading List - A large list of reading materials curated over many years, in all fields of math, from introductory texts to  more advanced stuff.

• This and this GeoGebra applet are very helpful for working with hyperbolic geometry.
