Webinar on Evolution Equations and Dynamical System

Resumo: I will present a result roughly states that, if one picks at random a spatially homogeneous spacetime, then, with positive probability, the geometry of the spacelike slices of the picked spacetime will oscillate in a chaotic manner as one approaches the initial singularity. I will also : - explain some nice mathematical properties of the finite dimensional dynamical system which describes the evolution of the geometry of the spacelike slices, - discuss further questions on the past asymptotic geometry of spatially homogeneous spacetimes. The main result I will discuss was obtained in collaboration with my student T. Dutilleul, building upon previous works by S. Liebscher, J. Härterig, K. Webster, M. Georgi, M. Reiterer and E. Trubowitz.
