This is the website of the research unit ( Forschergruppe) FOR 2402 - Rough paths, stochastic partial differential equations and related topics based in the greater Berlin area. Our research is funded by the German Science Foundation (DFG). The team comprises thirteen principal investigators based at Technische Universität Berlin (TU Berlin), Humboldt Universität Berlin (HU), Universität Potsdam (Potsdam) and the Weierstrass Institute for Applied Analysis and Stochastics Berlin (WIAS).General inquiries: Prof.s Peter K. Friz <friz@math.tu-berlin.de> and Wilhelm Stannat <stannat@math.tu-berlin.de>

18-May until 20-May: 7th Berlin-Oxford meeting (at WIAS, Berlin) 11-May: 4-May: 12.30 - 13.30 at TU Berlin MA748: 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: 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) 20-April 12:30 - 13:30 at TU Berlin MA 748:

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). 03-March 12:30 - 13:30 at TU Berlin MA 748: ****** NOTE unusual day******* We will first give a brief overview of some recent developments in KPZ and coupled KPZ equations. Then, we will formulate a conjecture on Glauber-Kawasaki dynamics leading to a nonlinear SPDE under a certain scaling limit.
