Abstract
This paper is concerned with mean square exponential stability of stochastic systems with interval time-varying delays. The time delay is any continuous function belonging to a given interval. By constructing a suitable augmented Lyapunov-Krasovskii functional combined with Leibniz-Newton’s formula, new delay-dependent sufficient conditions for the mean square exponential stability of the stochastic systems are first established in terms of LMIs.

The analysis of stochastic systems with respect to mean square stability of their equilibria has attracted many researchers
To the best of our knowledge, interval time-varying delay and mean square exponential stability of stochastic systems, non-differentiable time-varying delays have not been fully studied yet, which are important in both theories and applications

Summary
The analysis of stochastic systems with respect to mean square stability of their equilibria has attracted many researchers. To the best of our knowledge, interval time-varying delay and mean square exponential stability of stochastic systems, non-differentiable time-varying delays have not been fully studied yet (see, e.g., [21–26] and the references therein), which are important in both theories and applications. The delay-dependent mean square exponential stability of stochastic systems with interval time-varying delay conditions are formulated in terms of LMIs. The outline of the paper is as follows.
