Abstract:

We establish the contraction property between consecutive loops of adaptive hybridizable discontinuous Galerkin methods for the Poisson problem with homogeneous Dirichlet condition. The contractive quantity is the sum of the square of the $L^2$-norm of the flux error, which is not even monotone, and a two-parameter scaled error estimator, which quantifies both the lack of $H(\mathrm {div},\Omega )$-conformity and the deviation from a gradient of the approximate flux. A distinctive and novel feature of this analysis, which enables comparison between two nested meshes, is the lifting of trace residuals from inter-element boundaries to element interiors.
