A posteriori error estimates for nonlinear problems. Finite element discretizations of elliptic equations

By R. Verfürth

Abstract

Abstract. Using the abstract framework of [9] we analyze a residual a posteriori error estimator for space-time finite element discretizations of quasilinear parabolic pdes. The estimator gives global upper and local lower bounds on the error of the numerical solution. The finite element discretizations in particular cover the so-called θ-scheme, which includes the implicit and explicit Euler methods and the Crank-Nicholson scheme. 1
