ASYMPTOTIC STABILITY ANALYSIS OF RIEMANN-LIOUVILLE FRACTIONAL STOCHASTIC NEUTRAL DIFFERENTIAL EQUATIONS

Abstract

The novelty of our paper is to establish results on asymptotic stability of mild solutions in pth moment to Riemann-Liouville fractional stochastic neutral differential equations (for short Riemann-Liouville FSNDEs) of order alpha is an element of (21, 1) using a Banach's contraction mapping principle. The core point of this paper is to derive the mild solution of FSNDEs involving Riemann-Liouville fractional time-derivative by applying the stochastic version of variation of constants formula. The results are obtained with the help of the theory of fractional differential equations, some properties of Mittag-Leffler functions and asymptotic analysis under the assumption that the corresponding fractional stochastic neutral dynamical system is asymptotically stable.
