引进积集X×E上的一种拓扑结构和集合函数,用Young函数作用于极大算子,得到广义极大算子的Morrey空间有界性,推广了相关文献中的结果。
In this paper, the authorr introduces a type of topological structure in the Cartesian product and a set function, and obtains boundeness of generalized operators in Morrey spaces. The results improve and extend the known results.
