Abstract:

Let d be a positive ingter and N d denote  the d-dimensional lattice of positive integers. Let {Xn , n ∈ N d}be a same distribution NA random fields, put Sn = ∑k≤ n Xk, Sn(k)=Sn-Xk, if r >2, EX1 = 0 and σ2= Var(X1}, then there exists a positive constant M:=100√(r-2)(1+σ2) such that the following is equivalent:

(I)   E |X1|r (log|X1|)d-1-r/2 < ∞;

(II)   ∑n∈ Nd |n|r/2-2 P(max1≤ k≤ n |S n(k)| ≥ (2d+1 )ε √|n| log | n |) < ∞, ∨ε  > M;
 
(III)   ∑n ∈ N d |n|r/2-2 P(max1≤ k≤ n |Sk | ≥ ε √| n} log | n |) < ∞, ∨ε > M.
