An. Univ. Timiș., Ser. Mat.-Inform. 37, No. 1, 149-158 (1999).

Summary: Here, the author introduces a concept of exponential dichotomy for a stochastic evolution equation. Necessary and sufficient conditions for the exponential dichotomy are given. The obtained results are generalizations of the well-known results of R. Datko [SIAM J. Math. Anal. 3, 428-445 (1972)] and A. Ichikawa [Nonlinear Anal., Theory Methods Appl. 8, 805-815 (1984; Zbl 0547.47041)] on the stability of a class of stochastic equations.
