$B$值弱Orlicz $\alpha$拟鞅空间的原子分解

Abstract

Abstract:

As we all know, atomic decompositions is a powerful tool for studying martingale space, which can deal with problems concisely and effectively. In this paper, we define several types of weak Orlicz $\alpha $-quasi-martingale spaces and three types of quasi-atoms, and establish the strong atomic decomposition theorems. By atomic decompositions, we prove the boundedness of sublinear operators on these spaces and the continuous embedding relationship between these spaces.

Key words: Weak Orlicz spaces, $\alpha$-Quasi-martingale spaces, Atomic decompositions, Sublinear operators
