The Stochastic Analysis Seminar featuring Matthias Erbar from Universität Bielefeld will take place on 3 November 2026 at the Huxley Building, South Kensington Campus in London. The talk, titled 'Optimal transport and gradient flows for point processes', explores a theory of optimal transport for stationary random measures with a focus on stationary point processes. Erbar describes two types of distances on stationary probability measures geared towards different dynamics of point configurations, including one based on continuous displacement and another modelled on birth-death dynamics. The event is open to the public at no cost.
Matthias Erbar Title: Optimal transport and gradient flows for point processes Abstract I will describe a theory of optimal transport for stationary random measures with a focus on stationary point processes. We consider two types of distances on stationary probability measures on the configuration space geared towards different dynamics of point configurations. The first one is based on continuous displacement of points and leads to a two layer optimal transport problem with a probabilistic constraint. It gives rise to a natural notion of displacement interpolation between point processes and provides e.g. a characterisation of the evolution of infinitely many (interacting) Brownian motions as the gradient flow of the specific free energy. The second notion is based on a birth-death dynamic of points and is modelled on the Benamou-Brenier formula. In a perturbative regime around the Poisson process we obtain an EVI gradient flow characterisation of the associated Glauber dynamics. This is based on joint work with Martin Huesmann, Jonas Jalowy, Bastian Müller, and Hanna Stange.
