This paper provides an introduction to the mathematical analysis of the finite element method for second order elliptic boundary value problems. It includes: Some definitions concerning the various function spaces used; two model elliptic boundary value problems; the definitions of the finite element spaces used to approximate the solutions of the boundary value problems; existence, uniqueness and error estimates of the Galerkin method in the context of one of the model problems; local error estimates for the finite element method.
