摘要
This paper is devoted to presenting a new proof of boundedness of the commutator bI(alpha) - I(alpha)b (in which I-alpha and b are regarded as the Riesz and multiplication operators) acting on the Morrey space L-p,L-lambda under b is an element of BMO, and naturally, developing a regularity theory of commutators for Morrey-Sobolev spaces I-alpha(L-p,L-lambda) via a completely original iteration of I-alpha. Even in the special case of I-alpha(L-p), this is a new theory.
