Mathematical Olympiads

Between 2012 and 2017 I got involved in several activities related to mathematical competitions:

  • training sessions for pre-university students in Girona and in Barcelona,
  • organization of some olympiads and
  • journals dedicated to mathematical problems.

Most of my contributions were explanations and reinterpretations of problems that I had previously seen (many by José Luis Díaz-Barrero and even more of unknown author) and were recorded only in undecipherable handwritten notes and hopefully in some students’s memories. Despite this, I typed a few documents that I will share here.
