Abstract. We prove theorems on the boundedness of commutators [a, H The main impacts of these theorems are 1. the use of CMOs-class of coefficients a for the commutators; 2. the general setting when the function ϕ defining the Morrey space and the weight w are independent of one another and the weight w is not assumed to be in Ap; 3. recovering the Sobolev-Adams exponent q instead of SobolevSpanne type exponent in the case of classical Morrey spaces 4. boundedness from local to global Morrey spaces; 5. the obtained estimates contain the parameter s > 1 which may be arbitrarily chosen. Its choice regulates in fact an equilibrium between assumptions on the coefficient a and the characteristics of the space. The obtained results are new also in non-weighted case.Mathematics Subject Classification. 46E30, 42B35, 42B25, 47B38.
