On the Multilinear Fractional Integral Operators with Correlation Kernels

Zuoshunhua Shi, Di Wu, Dunyan Yan

摘要:

本文研究了一类具有相关核$\prod_{1\leq i<j \leq k}|x_i-x_j|^{-α_{ij}}$的多线性分数次积分算子。得到了这些算子从$L^{p_1}\times \cdots \times L^{p_k}$有界到$L^q$的充要条件.作为结果,我们还得到了这些算子从$L^{p_1}\times \cdots \times L^{p_k}$到$BMO$的端点估计。

英文摘要:

In this paper, we study a class of multilinear fractional integral operators which have correlation kernels $\prod_{1\leq i<j \leq k}|x_i-x_j|^{-α_{ij}}$. The necessary and sufficient conditions are obtained under which these oprators are bounded from $L^{p_1}\times \cdots \times L^{p_k}$ into $L^q$. As a consequence, we also get the endpoint estimates from $L^{p_1}\times \cdots \times L^{p_k}$ to $BMO$ of these operators.
