关于大索伯列夫空间和Banach函数空间的点态描述

On grand Sobolev spaces and pointwise description of Banach function spaces

Pankaj Jain, Anastasia Molchanova, Monika Singh, Sergey Vodopyanov

摘要:

利用格的性质得到了属于函数空间的函数的点态描述。特别地,只要Hardy-Littlewood极大算子是有界的,它对Banach函数空间也是有效的.我们还研究了定义在任意开集(有限或无限测度)上的加权大索伯列夫空间,并给出了它们的逐点描述。

英文摘要:

We obtain a pointwise description of functions belonging to function spaces with the lattice property. In particular, it is valid for Banach function spaces provided that the Hardy-Littlewood maximal operator is bounded. We also study weighted grand Sobolev spaces, defined on arbitrary open sets (of finite or infinite measure), and provide pointwise description of them.
