Abstract

In view of a growing number of stochastic partial differential equation (SPDE) models used in the natural sciences as well as in mathematical finance, their data-based calibration has become an increasingly active field of research during the last years. In this talk we study non-parametric estimation for SPDEs when the solution field is observed discretely in time and space with a focus on SPDEs on bounded multi-dimensional domains. We will derive rates of convergence as well as central limit theorems for the constructed estimators.
