It is shown that this notion is stable under domination of quadratic forms. As applications measure perturbations of quasi-regular Dirichlet forms, Cheeger energies on metric measure spaces and Schrödinger operators on manifolds are studied. Along the way a characterization of the Sobolev space with Dirichlet boundary conditions on domains in infinitesimally Riemannian metric measure spaces is obtained.","lang":"eng"}],"article_number":"38","article_processing_charge":"Yes (via OA deal)","has_accepted_license":"1","day":"01","month":"07","citation":{"ieee":"M.
