Trace theorems on Herz-Morrey spaces with applications to Sobolev type inequalities
摘要
In this paper, we prove the trace theorems in the setting of Riesz potential operator for Herz-Morrey spaces and present some examples to illustrate the optimality of certain parametric conditions. As an application we prove the same inequalities including Sobolev-type inequalities and Gagliardo-Nirenberg-Sobolev inequality on Herz-Morrey spaces under some proper assumptions on the exponents. We will also establish the Sobolev embedding theorem for Herz-Morrey Sobolev spaces.
