On the Asymptotic Equivalence of Infinite-Dimensional Stochastic Systems
摘要
We generalize the classical Levinson theorem on the asymptotic equivalence on infinite-dimensional stochastic systems. In particular, for a given system of linear stochastic differential equations, we construct a system of ordinary differential equations whose solutions are characterized by the behavior at infinity similar to the behavior of solutions of the original system both in the mean-square sense and with probability 1.
