In this paper we present a definition of Sobolev spaces with respect to general
measures, prove some useful technical results, some of them generalizations of classical results with Lebesgue measure and find general conditions under which these spaces are comIn this paper we present a definition of Sobolev spaces with respect to general
measures, prove some useful technical results, some of them generalizations of classical results with Lebesgue measure and find general conditions under which these spaces are complete. These results have important consequences in approximation theory. We also find conditions under which the evaluation operator is bounded.[+][-]
