The following topics will be treated: * Classification of PDEs. * Some elements of functional analysis and approximation theory. * Variational formulation and Ritz Galerkin approximation, in particular for elliptic PDEs. * Examples of finite elements. * Error estimates. In addition, a selection of the following topics will receive attention: * FEM for saddle point problems. * Nonconforming finite elements. * Iterative methods for solving the large linear systems resulting from a FEM discretization. * Adaptive methods. * Nonstationary PDEs.
