Why hyperbolic Kac Moody algebras are so horrendously complicated, and what this could mean for physics

by Prof. Hermann Nicolai

Wednesday 11 Sept 2024, 14:30 → 16:30 Europe/Rome

1/1-3 - Aula B (Dipartimento di Fisica e Astronomia - Edificio Marzolo)

In this talk I will review some basic features of indefinite, and more specifically hyperbolic Kac Moody algebras, and report on ongoing (and still unpublished) work on the simplest such algebra, of rank three. Possible implications for the quantum cosmology of the Big Bang will be briefly discussed, see also Class.Quant.Grav. 38 (2021) 18, 187001.
