On Minimal Inequalities of Demisubmartingales
摘要/Abstract
摘要：
弱鞅是随机序列的一种特殊形式，并且是均值为0的独立随机变量和均值为零的相协随机变量.弱鞅不等式在随机分析中占有重要地位.利用一些基本不等式建立了弱半鞅和弱鞅的一些极小值不等式，这些不等式推广和改进了前人的结果.
Abstract：
As we all know,demimartingales as a special kind of random variable sequence.It's also the independent random variable of mean zero and mean zero associated random variable.In this paper, we establish some minimal inequalities for demisubmartingales and demimartingales by using some elementary inequalities.those inequalities generalize and improve the results in literature.
