02/04/2025 - 4:00pm I will show that the space of pointed infinite volume hyperbolic 3-manifolds is connected but not path connected. This space is equipped with the geometric topology, in which two pointed manifolds are close if they are almost isometric on large neighborhoods of their basepoints. The proof of connectivity will be an application of the density theorem for Kleinian groups. I will then use a combination of results on representations of Kleinian groups and Chabauty spaces of subgroups to construct an infinite family of path components of this space. Location:

02/04/2025 - 4:00pm In this talk we will review some recent developments in the framework of hypocoervicity to obtain quantitative convergence estimate of classical and quantum dynamics, with focus on underdamped Langevin dynamics for sampling and Lindblad dynamics for open quantum systems. If time permits, we will also discuss some related problems in two-timescale gradient descent and ascent dynamics. Location:
