Asymptotic Exponential Stability of Stochastic Partial Differential Equations with Delay

Abstract

Sufficient conditions for pathwise asymptotic exponential stability of the solution of the stochastic PDE with delay d x t = Ax tdt + B(xp(t)) dwt are given. The assumptions on the operators A and B are essentially the same as in the case without delay. In addition, our deduction also shows an alternative proof for some of the results in this case. In fact, the crucial difference is that we do not use the operator P employed by Haussmann and Ichikawa.
