摘要
In this paper we study mixed norm boundedness for fractional integrals related to Laplace-Beltrami operators. on compact Riemannian symmetric spaces of rank one. The key point is the analysis of weighted inequalities for fractional integral operators associated to trigonometric Jacobi polynomials expansions. In particular, we find a novel sharp estimate for the Jacobi fractional integral kernel with explicit dependence on the type parameters. Published by Elsevier Inc.
