Abstract: Using the relation between homogeneous Morrey-Herz spaces MKα,λp,q(Rn) and homogeneous Herz spaces Kα,pq(Rn), some results on Kα,pq(Rn) were extended. The CBMO estimates on MKα,λp,q(Rn) were established for the commutator TbΩ,l and multilinear operators TAΩ,l of fractional integrals with rough kernel. In the meanwhile, the corresponding results for maximal commutators MbΩ,l and multilinear maximal operators MAΩ,l of fractional integrals were obtained.

Key words: commutator, multilinear operator, fractional integral, rough kernel, MorreyHerz space, central bounded mean oscillation space
