Course Description

Overview

Explore a lecture on convergence rates for Galerkin approximations of generalized Whittle-Matern fields in Hölder and Sobolev norms. Delve into the analysis of Gaussian random fields with covariance operators given by negative fractional powers of second-order elliptic differential operators. Examine both spectral Galerkin methods and finite element methods, with a focus on their applicability to non-stationary fields on non-standard domains. Learn about optimal strong convergence rates, error analysis, and key elements of deterministic error proofs. Gain insights into numerical simulations and the practical implications of this research, which is particularly relevant for models involving Gaussian fields with adjustable correlation length and smoothness.
