Summary
Let {X j} be i.i.d. r.v.'s taking values in a separable Banach space, and let \(s_n = \sum\limits_{j = 1}^n {X_j } \). The almost sure limiting behavior of the normalized random set of increments {b −1n (S k+h-Sk): 1≦k≦n, 1≦h≦an} for a broad class of sequences a n→∞ with corresponding normalizations b n is determined. When a n/log n→∞, the results generalize and improve some recent work of Csörgő and Révész and some previous work of Lai. When a n =clog n, the results generalize and refine in a certain sense the Erdös-Rényi law of large numbers. The case a n/logn→0 is also studied.
