Kurzfassung englisch:
Abstract. We consider the approximation of singularly perturbed linear second-order boundary value problems by hp-finite element methods. In particular, we include the case where the
associated differential operator may not be coercive. Within this setting we derive an a posteriori error estimate for a natural residual norm. The error bound is robust with respect to the
perturbation parameter and fully explicit with respect to both the local mesh size h and the polynomial degree p.
