The discrete compactness property for anisotropic edge elements on polyhedral domains. (English) Zbl 1281.78014

The author proves the validity of the discrete compactness property for edge elements of any order on a class of anisotropically refined tetrahedral meshes on general Lipschitz polyhedral domains. Both edge and corner refinements are considered. The class of meshes considered includes the anisotropic graded meshes designed by T. Apel and S. Nicaise [Math. Methods Appl. Sci. 21, No. 6, 519–549 (1998; Zbl 0911.65107)].
