关于N^+类函数

给出Ｎ＋类函数的一个便于应用的等价定义，证明了在Ｎ中有界的函数类Ｍ（ｆ）是Ｎ＋的子集，并对ＨｐＮ＋Ｎ这一已知结果给以简明的重证．

CHARACTERIZATION OF MAXIMAL OPERATORS IN ORLICZ-MORREY SPACES OF HOMOGENEOUS TYPE

. In this paper,the characterization of boundedness of Hardy-Littlewood maximal operators in Orlicz-Morrey spaces LΦφ（X,μ） of homogeneous type is founded.
