摘要
设T为强奇异积分算子.T与函数b生成的交换子由Tbf=bT(f)-T(bf)给出.当b属于某些Campanato空间时,本文给出了交换子Tb从Morrey空间到Campanato空间有界的充分条件.
Let T be a strongly singular integral operator.The commutator generated by T and a function b is given by Tbf=bT(f)−T(bf).In this paper,some sufficient conditions are given for the boundedness of the commutator Tb from Morrey spaces to Campanato spaces when b belongs to certain Campanato spaces.
