Multilinear $\theta$-type Calderón--Zygmund operators and commutators on products of weighted Morrey spaces

In this paper, we consider the boundedness properties of multilinear $\theta$-type Calderón–Zygmund operators $T_{\theta }$ recently introduced in the literature. First, we prove strong type and weak type estimates for multilinear $\theta$-type Calderón–Zygmund operators on products of weighted Morrey spaces with multiple weights. Then we discuss strong type estimates for both multilinear commutators and iterated commutators of $T_{\theta }$ on products of these spaces with multiple weights. Furthermore, the weak end-point estimates for commutators of $T_{\theta }$ and pointwise multiplication with functions in bounded mean oscillation are established too.
