DESCRIPTION:Speaker: Matthias Erbar\nhosted by Jan Maas\nAbstract: In this
talk I will present a new point of view on the spatially homogeneous Boltz
mann equation viewing it as the gradient flow of the entropy. This gradien
t flow structure relies on a new notion of distance between probability me
asures that takes the collision process between particles into account and
takes over the role of the Wasserstein distance. As two applications of t
his point of view I will present a time-discrete variational approximation
scheme for the homogeneous Boltzmann equation and a new and simple proof
for the convergence of Kac's random walk to the Boltzmann equation.\n
