Title: Convergence and quasi optimality of adaptive hybridizable discontinuous Galerkin methods

Abstract: We establish the convergence and quasi-optimality of adaptive hybridizable discontinuous Galerkin (AHDG) methods for the Pois- son problem. We prove that the so-called quasi-error, that is, the sum of an energy-like error and a suitably scaled error estimator, contracts between two consecutive loops. Moreover, we show that the AHDG methods achieve optimal rates of convergence.
