Estimates for multilinear commutators of generalized fractional integral operators on weighted Morrey spaces

He Sha, Tao Xiangxing

Let $L$ be the infinitesimal generator of an analytic semigroup on $L^2({\mathbb{R}}^n)$ with Gaussian kernel bounds, and let $L^{-\alpha /2}$ be the fractional integrals of $L$ for $0<α<n…
