Abstract
The topic of this thesis contains influences of numerical mathematics, functional analysis and approximation theory, as well as stochastic respectively uncertainty quantification. The focus is beside the full space-time weak formulation of linear parabolic partial differential equations and their properties, especially the stability of their Petrov-Galerkin approximations. Moreover, the concept of space-time weak formulations is extended to parabolic differential equations with random coefficients, where an additional central aspect of this thesis is the existence of moments of the solution and the optimality of its Petrov-Galerkin solution. In the scope of this work a Matlab code for the numerical realization of the Petrov-Galerkin approximation with B-splines of arbitrary order was developed.
