本文在抽象Wiener空间的框架下,定义了随机变量等价类的凸性和凸性的概念。作为应用,我们表明,有限维情况下的一些重要的不等式有其自然的对应在此设置。
Abstract We define, in the frame of an abstract Wiener space, the notions of convexity and of concavity for the equivalence classes of random variables. As application we show that some important inequalities of the finite dimensional case have their natural counterparts in this setting.
