Hybrid high-order methods for variable-diffusion problems on general meshes. (Méthodes hybrides d’ordre élevé pour des problèmes à diffusion variable sur des maillages généraux.) (English. French summary) Zbl 1308.65196

Summary: We extend the hybrid high-order method introduced by the authors and S. Lemaire [Comput. Methods Appl. Math. 14, No. 4, 461–472 (2014; Zbl 1304.65248)] for the Poisson problem to problems with heterogeneous/anisotropic diffusion. The cornerstone is a local discrete gradient reconstruction from element- and face-based polynomial degrees of freedom. Optimal error estimates are proved.
