The authors study the boundedness for a large class of sublinear operator 𝑇 generated by Calderón-Zygmund operator on generalized Morrey spaces 𝑀 𝑝 , 𝜑 . As an application of this result, the boundedness of the commutator of sublinear operators 𝑇 𝑎 on generalized Morrey spaces is obtained. In the case 𝑎 B M O ( 𝑛 ) , 1 < 𝑝 < and 𝑇 𝑎 is a sublinear operator, we find the sufficient conditions on the pair ( 𝜑 1 , 𝜑 2 ) which ensures the boundedness of the operator 𝑇 𝑎 from one generalized Morrey space 𝑀 𝑝 , 𝜑 1 to another 𝑀 𝑝 , 𝜑 2 . In all cases, the conditions for the boundedness of 𝑇 𝑎 are given in terms of Zygmund-type integral inequalities on ( 𝜑 1 , 𝜑 2 ), which do not assume any assumption on monotonicity of 𝜑 1 , 𝜑 2 in 𝑟 . Conditions of these theorems are satisfied by many important operators in analysis, in particular pseudodifferential operators, Littlewood-Paley operator, Marcinkiewicz operator, and Bochner-Riesz operator.
