SUMMARY:CMM PDE Seminar “Future stability of Maxwell-Jüttner equilibria and vacuum for the massless Boltzmann equation on FLRW spacetimes”
DESCRIPTION:Abstract: In this talk, we will consider the massless Boltzmann equation on FLRW spacetime with spatial topology $\mathbb{T}^3$ in the linear and decelerated expanding regimes, where the scale factor is $t^q$ with $q\in (0,1]$. In these backgrounds, the massless Boltzmann equation admits a non-stationary Maxwell-Jüttner equilibrium that maximises the entropy of the system. In this work, this equilibrium is shown to be non-linearly stable for the massless Boltzmann equation in the case of hard ball interaction. We will also discuss the non-linear stability of the vacuum solution when $q\in (1/3,1]$. This is joint work with Robert M. Strain (University of Pennsylvania) and Martin Taylor (Imperial College London).\nFor those unable to attend in person, the talk will also be available via Zoom at the following link: https://uchile.zoom.us/j/97781230158?pwd=MDIJ5OSVvuObCde6BEes5HcHwxeSa8.1\nSpeaker: Renato Velozo Ruiz (Universidad de Chile)\n
