New Sparse Domination and Weighted Estimates for Fractional Operators Beyond Calderón-Zygmund Theory

The Anh Bui, Linfei Zheng

Let $L$ be a closed, densely defined operator on $L^2({\mathbb{R}}^n)$ satisfying suitable $L^p-L^q$ off-diagonal estimates of order $\kappa >0$. This paper aims to investigate the two-we…
