主要讨论两类带变量核的积分算子的性质,证明了带变量核的分数次积分算子TΩ,μ是从B^q,λ1^(R^n)到B^q,λ2^(R^n)上的有界算子,其交换子T^bΩ,μ是从B^p,λ1^(R^n)到B^q,λ2^(R^n)上的有界算子.对于变量核的奇异积分及其交换子,也有类似的结论.
In this paper we discuss the properties of two kinds of integral operator with variable kernel and prove that fractional integral operator with variable kernel TΩ,μ is bounded from B^q,λ^(R^n). We also show that the commutator T^bΩ,μ is bounder from B^q,λ1(R^n) into B^q,λ2(R^n). Similar results are obtained for singualar integral and its commutators.
