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.
