Stein-Weiss inequality for local mixed radial-angular Morrey spaces

Open Mathematics, 2022
In this article, a generalization of the well-known Stein-Weiss inequality for the fractional integral operator on functions with different integrability properties in the radial and the angular direction in local Morrey spaces is established.
