Dr. Hermann Nicolai del Albert Einstein Institut, Berlin va exponer sobre

*"Cosmological Billiards: an **introduction"**
Abstract: "The classic analysis of space-⁠like singularities in Einstein's
theory by Belinski, Khalatnikov and Lifshitz (BKL) has revealed a very
complicated behavior of the metric near the singularity. More recently 
the occurrence of chaotic metric oscillations has been linked to an 
infinite dimensional symmetry of hyperbolic Kac--Moody type, which 
vastly extends
known symmetries of Einstein's equations in certain reductions (such as 
the Ehlers and the Geroch group). In this talk I will review these 
developments at an introductory level."
