Abstract

In this article, we study the fractional spherical maximal function and its lacunary counterpart. We study the necessary and sufficient conditions for LpLqL^p-L^q boundedness of both maximal functions. In particular, we prove the restricted weak type estimate for both full and lacunary fractional spherical maximal functions at the boundary of the maximal LpLqL^p-L^q bounded regions.
