Boundedness criterion for sublinear operators and commutators on generalized mixed Morrey spaces

Abstract

In this paper, the author studies the boundedness for a large class of sublinear operator $T_\alpha, \alpha\in[0,n)$ generated by Calder{\'o}n-Zygmund operators ($\alpha=0$) and generated by fractional integral operator ($\alpha>0$) on generalized mixed Morrey spaces $M^\varphi_{\vec{q}}(\Bbb R^n)$. Moreover, the boundeness for the commutators of $T_\alpha, \alpha\in[0,n)$ on generalized mixed Morrey spaces $M^\varphi_{\vec{q}}(\Bbb R^n)$ is also studied. As applications, we obtain the boundedness for Hardy-Littlewood maximal operator, Calder\'on-Zygmund singular integral operators, fractional integral operator, fractional maximal operator and their commutators on generalzied mixed Morrey spaces.
