The Boundedness of Fractional Integral Operators in Local and Global Mixed Morrey-type Spaces

Houkun Zhang, Jiang Zhou

摘要:

本文引入了局部与整体混合Morrey型空间,并研究了这类空间的一些性质。然后,分别在混合范数Lebesgue空间和局部混合Morrey型空间中研究了分数次积分算子$I_α$有界的必要条件.最后,利用Hardy算子在加权Lebesgue空间中的有界性,得到了$I_α$的有界性.作为推论,我们得到了$I_α$在混合Morrey空间(\hyperlink{Corollary 5.6}{Corollary 5.6})和混合Lebesgue空间(\hyperlink{Corollary 5.7}{Corollary 5.7})中的有界性.特别地,\hyperlink{Corollary 5.7}{Corollary 5.7}得到了一个充分和必要条件.

英文摘要:

In this paper, we introduced the local and global mixed Morrey-type spaces, and some properties of these spaces are also studied. After that, the necessary conditions of the boundedness of fractional integral operators $I_α$ are studied respectively in mixed-norm Lebesgue spaces and the local mixed Morrey-type spaces. Last but not least, the boundedness of $I_α$ is obtained by Hardy operators' boundedness in weighted Lebesgue spaces. As corollaries, we acquire the boundedness of $I_α$ in mixed Morrey spaces(\hyperlink{Corollary 5.6}{Corollary 5.6}) and mixed Lebesgue spaces(\hyperlink{Corollary 5.7}{Corollary 5.7}) respectively. Particularly, \hyperlink{Corollary 5.7}{Corollary 5.7} obtains a sufficient and necessary condition.
