摘要
This paper considers compactness of the commutator[b,I_(α)]i(i=1,2),where I_(α)is a bilinear fractional integral operator,and b is a function in generalized Campanato spaces with variable growth condition.The author gives sufficient conditions for the compactness of[b,I_(α)],(i=1,2)from the product of generalized Morrey spaces to generalized Morrey spaces.
本文研究双线性分数次积分算子与带变量增长条件的广义Campanato空间函数b生成的交换子[b,I_(α)]i(i=1,2)在广义Morrey空间的紧性。给出了[b,I_(α)]i(i=1,2)从广义Morrey空间的乘积空间到广义Morrey空间紧性的充分条件。
