摘要
In this paper, we introduce a new concept of Stepanov-like almost automorphy (or S-2-almost automorphy) for stochastic processes. We use the results obtained to investigate the existence and uniqueness of a Stepanov-like almost automorphic mild solution to a class of nonlinear stochastic differential equations in a real separable Hilbert space. Our main results extend some known ones in the sense of square-mean almost automorphy. (C) 2010 Elsevier Ltd. All rights reserved.
