Commutator Theorems for Fractional Integral Operators on Weighted Morrey Spaces

Zengyan Si

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

Necessary and sufficient conditions for boundedness of commutators of the general fractional integral operators on weighted Morrey spaces

Zengyan Si, Fayou Zhao

We prove that $b$ is in $Lip_{\bz}(\bz)$ if and only if the commutator $[b, L^{- α /2}]$ of the multiplication operator by $b$ and the general fractional integral operator $L^{- α /2}$ …
