Next talk: How playing a game gives you the largest collection of numbers (Hackenbush)
Date: Thursday, 26 March 2026, 2:00 – 3:00 pm.
Room: 278
Speaker: Aldayr de Jesús Silva Contreras
Abstract: John H. Conway was one of the most free-spirited mathematicians of all time. A testament to this can be seen throughout his works and through some funny anecdotes about him told by his peers and students. In particular, this can be felt by going through his collection of books titled Winning Ways for your mathematical plays.
In this one board seminar, I will discuss one particular game described in the first volume of this collection of books and how this led him to the discovery of the largest collection of numbers, and I will also share some remarks on this fascinating construction.

This seminar is organized for early-career researchers from IMI, ICMS and the faculty. This would be a great opportunity for young researchers to meet and exchange ideas in an informal and interactive setting.
We meet every Thursday at 2:00 pm in room 478.
