Mixed radial-angular integrabilities for Hardy type operators. (English) Zbl 1527.42020

Summary: In this paper, we are devoted to studying the mixed radial-angular integrabilities for Hardy type operators. As an application, the upper and lower bounds are obtained for the fractional Hardy operator. In addition, we also establish the sharp weak-type estimate for the fractional Hardy operator.
