Characterization of CMO via compactness of the commutators of bilinear fractional integral operators

Dinghuai Wang, Jiang Zhou, Wenyi Chen

Let $I_{\alpha }$ be the bilinear fractional integral operator, $B_{\alpha }$ be a more singular family of bilinear fractional integral operators and $\vec{b}=(b,b)$. Bényi et al. in \cite{B1} sho…
