On nonlinear Markov processes in the sense of McKean

We introduce and study nonlinear Markov processes in the sense of McKean, initiate a theory of these processes, and present a large class of new examples. More precisely, we construct nonlinear Markov processes with one-dimensional time marginals given as solution flows of nonlinear Fokker-Planck equations. These processes are given by path laws of weak solutions to the corresponding distribution-dependent stochastic differential equation. Our results apply to nonlinear Fokker-Planck equations with locally density-dependent coefficients, which includes many important nonlinear parabolic PDEs. Thus, we establish a one-to-one correspondence between solution flows of such PDEs and nonlinear Markov processes. Important examples are porous media and Burgers equation, as well as the 2D vorticity Navier-Stokes equation.

The theory of paracontrolled calculus made it possible to obtain the local well-posedness results for some singular stochastic PDEs. In this talk, I explain how to obtain the global existence for two examples: (a) multi-component KPZ equation and (b) stochastic CGL equation on the three-dimensional torus. A probabilistic approach is used in (a) and an analytic approach is used in (b).

27-April:12:30 - 13:30 at TU Berlin MA 748: María J. Garrido-Atienza (Sevilla), Title: Exponential Stability of solutions to SPDEs driven by fractional Brownian motion

In this talk we are concerned with the study of the longtime behavior of stochastic evolution equations driven by a fractional Brownian motion (fBm). We will analyze different approaches and consider both the cases of an fBm with Hurst parameter $H\in (1/2,1)$ and $H\in (1/3,1/2]$. This talk is based on some joint works with Duc Hoang Luu (Max-Planck Institut of Leipzig), A. Neuenkirch (University of Mannheim) and B. Schmalfuss (University of Jena)

We show well-posedness for the parabolic Anderson model on 2-dimensional closed Riemannian manifolds. To this end we extend the notion of regularity structures to curved space, and explicitly construct the minimal structure required for this equation. A central ingredient is the appropriate re-interpretation of the polynomial model, which we build up to any order. This is joint work with Antoine Dahlqvist (Cambridge) and Bruce Driver (UCSD).
