Abstract

In this paper we develop an hphp-adaptive procedure for the numerical solution of general second-order semilinear elliptic boundary value problems, with possible singular perturbation. Our approach combines both adaptive Newton schemes and an hphp-version adaptive discontinuous Galerkin finite element discretisation, which, in turn, is based on a robust hphp-version a posteriori residual analysis. Numerical experiments underline the robustness and reliability of the proposed approach for various examples.
