Approximation in generalized Morrey spaces

In this paper we study the approximation of functions from generalized Morrey spaces by nice functions. We introduce a new subspace whose elements can be approximated by infi nitely diff erentiable compactly supported functions. This provides, in particular, an explicit description of the closure of...

Resumo:In this paper we study the approximation of functions from generalized Morrey spaces by nice functions. We introduce a new subspace whose elements can be approximated by infi nitely diff erentiable compactly supported functions. This provides, in particular, an explicit description of the closure of the set of such functions in generalized Morrey spaces.
