鞅的极大函数的Φ－可积性

Φ-Integrablity for the Maximal Function of Martingal

设ｆ是的极大函数，本文讨论ｈ（ｆ）的几种Φ－可积性（其中ｈ，Φ是凸函数），并给出相关不等式中的常数ｃ的一个上界。

Let f be the maximal function of martingale. We discuss several Φ-integrabilities of the h(f) (Where h and Φ are covex function). And, the some upper bound of the constant in the concerning ineqalities are presented.
