Abstract

In this paper, we study integral operators \begin{equation*} T_\alpha f(x)=\int_{\mathbb{R}^{n}}K(x,y) f(y)dy, \end{equation*} with kernels K(x,y)=k1(xA1y)...km(xAmy),K(x,y)= k_1( x- A_1y)...k_m( x-A_my), where ki(x)=Ωi(x)xn/qik_i(x)=\frac{\Omega_i(x)}{|x|^{n/q_i}} and Ωi:RnR\Omega_i: \mathbb{R}^n\to \mathbb{R} are homogeneous functions of degree zero, satisfying a size and a Dini condition, AiA_{i} are certain invertible matrices, and nq1++nqm=nα,\frac n{q_1}+\dots+\frac n{q_m}=n-\alpha, 0α<n.0\leq \alpha <n. We obtain the Hwpp(Rn)Lwqq(Rn)H^{p}_{w^p}(\mathbb{R}^{n})-L^{q}_{w^q}(\mathbb{R}^{n}) boundedness of these operators, for a class of Muckenhoupt weights ww, satisfying the condition \begin{equation*} w(A_ix)\leq cw(x), \end{equation*} a.e.xRna.e.x\in\mathbb{R} ^n , 1im1\leq i\leq m.
