在弱鞅序列{S_n,n≥1}的背景下,给出了序列{c_nS_n,n≥1}和{c_ng(S_n),n≥1}的一类极小值不等式。所得结论推广了已有文献中的相关结果。
In the background of the demimartingale sequence { Sn, n≥1 } , a class of minimal inequalities for the se-quence {c,,Sn, n≥1 } and {cng(Sn), n ≥1 [ are given in this paper. These results generalize the corresponding results in recent papers.
