AN IMPROVED RESULT OF EXPONENTIAL STABILITY OF STOCHASTIC SEMILINEAR EVOLUTION EQUATIONS

Kai Liu, Anyue Chen

Abstract


Sufficient conditions for the exponential stability of a class ofnonlinear, non-autonomous stochastic differential equations in infinitedimensions are studied. The analysis consists of introducing a suitableapproximating solution systems and using a limiting argument to pass onstability of strong solutions to mild ones. As a consequence, the classicalcriteriaof stability in A. Ichikawa [8] are improved and extended to cover a class ofnon-autonomous stochastic evolution equations.Two examples are investigated to illustrate our theory.
