Exponential stability in mean square for neutral stochastic partial functional differential equations with impulses

We discuss the exponential stability in mean square of mild solution for neutral stochastic partial functional differential equations with impulses. by applying impulsive gronwall-bellman inequality,the stochastic analytic techniques,the fractional power of operator,and semigroup theory,we obtain some completely new sufficient conditions ensuring the exponential stability in mean square of mild solution for neutral stochastic partial functional differential equations with impulses. finally,an example is provided to illustrate the obtained theory. © 2013 nan ding.
