The goal of this seminar is to understand the famous McKay equation $$196884 = 196883 + 1\,. $$ The left-hand side is the first non-trivial coefficient of the modular invariant \(j\)-function. On the right hand-side are the dimensions of the smallest irreducible representations of the largest sporadic simple group, the Monster group \(\mathbb{M}\).

All necessary information can be found here.

Talks will take place Friday 12:00 - 14:00 (CET) via Zoom. If you are interested in participating, please send a mail to the organizer (buelles(at)math.ethz.ch) to receive the Zoom ID and password.
