The goal of this special session is to bring together people working in Analysis, Geometry or Probability and to focus on recent developments in Geometric Analysis on Riemannian manifolds, Diffusion processes on fractal and singular spaces, Stochastic differential geometry, Stochastic analysis in infinite dimensions.
It is well-known that Brownian motion and martingales on manifolds or vector bundles connect local and global geometry in an intrinsic way, and that many questions related to the geometry of Laplace operators have a direct probabilistic counterpart. Furthermore probabilistic methods often extend naturally to areas, like singular spaces or infinite dimensional spaces, where standard tools of differential analysis or PDE methods fall short. This Mini-Symposium intends to focus on recent progress in these areas.
