摘要: 设{Xn,n ≥ 1}是在S={1,2,…,N}中取值的随机变量序列,其分布为p(x1,…,xn),limn inf[p(X1,…,Xn)]1/n与limn sup[p(X1,…,Xn)]1/n称为AEP型极限.利用这些极限该文得到{Xn,n ≥ 1}的若干强偏差定理,即一类用不等式表示的强极限定理.

Abstract: Let {Xn, n ≥ 1} be a sequence of random variables taking values in S={1,2,… N} with the joint distribution p(x1,…,xn). limn inf[p(X1,…,Xn]1/n and limn sup[p(x1,…,xn]1/n are called the AEP-like limits. In virtue of these limits, some strong deviation theorems, namely a class of strong limit theorems represented by inequalities are obtained.
