Abstract

In this paper, we focus on a class of fractional type integral operators that can be served as extensions of Riesz potential with kernels K(x,y)=Ω1(xA1y)xA1ynq1Ωm(xAmy)xAmynqm,K(x,y)=\frac{\Omega_1(x-A_1 y)}{|x-A_1 y |^{\frac{n}{q_1}}} \cdots \frac{\Omega_m(x-A_m y)}{|x-A_m y |^{\frac{n}{q_m}}}, where α[0,n),m1,i=1mnqi=nα\alpha\in [0,n), m\geqslant1, \sum_{i=1}^m\frac{n}{q_i}=n-\alpha, {Ai}i=1m\{A_i\}^m_{i=1} are invertible matrixes, Ωi\Omega_i is homogeneous of degree 0 on Rn\R^n and ΩiLpi(Sn1)\Omega_i\in L^{p_i}(S^{n-1}) for some pi[1,)p_i\in [1,\infty). Under appropriate assumptions, we obtain the weighted LpL^p estimates as well as weighted Hardy estimates of the commutator for such operators with BMOBMO-type function. In addition, we acquire the boundedness of these operators and their commutators with a function in Campanato space on Orcliz-Morrey spaces as well as the compactness for such commutators in a special case: m=1m=1 and A=IA=I.
