几乎处处中心极限定理;强相依高斯序列;权重
其中I(·)为示性函数, φ() x为标准正态密度函数.
为证明定理,需用到以下几个引理:
其中ε由(2)式确定.
引理1的证明类似于蔺富明[7]引理2.1的证明过程.
其中ε由(2)式确定.
引理2的证明运用引理1以及正态比较引理易证得.
引理3令ξ1,ξ2,…是有界随机变量,存在δ>0,使得
引理3的证明类似于吴群英[8]引理2的证明过程.
由注1[9],可不妨假设0<β<,因此下面仅对0<β<进行证明.当满足定理1的条件时,运用Leadbetter[10]推论6.5.2,有
由Toeplitz引理以及(4)式可得
因此,要证明(3)式,只需证明
由引理3,要证明(5)式只需证明存在δ>0有
由慢变化函数的性质和ηk有界可得
对于B,引用文献[7]中(26)式中对H的计算,有|E(ηη)|≤,由文献[9]中(11)式和(13)式对S1n的计算,取σ=min-1,1},有

Almost sure limit theorems for maxima of the strongly dependent Gaussian sequences
LIU Yanping,WU Qunying,YANG Fei
(College of Science,Guilin University of Technology,Guilin 541004,China)
Discussed almost sure limit theorems for maxima of strongly dependent Gaussian sequence. The almost sure limit theorem with logarithmic mean from Lin Fuming was extended to weight(0≤β<)under some mild conditions.
