关于ρ-混合序列的完全收敛性

Let l (x) andβ(x) be even positive fun(?)tions. Suppose there is a censtant θ>0 such that β(x)/x~θ, x~2/β(x) and l(x) (x>0) are monotone nondecreasing Denote α(x) is the converse funotion of β(x). Theerem 1 Suppose there is a constant 0<ε_0<1 such that β(x)l(β(x))/x and x~(2-ε_0)/(β(x)l(β(x))) are monotene nondecreasing. Let {X_k} be a ρ-mixing sequence of identically distributed random varibles with EX_1=0 and Eβ(X_1)l(β(|X_1|))
