The main purpose of this paper is to investigate the existence and Ulam-Hyers stability (U-
Hs) of solutions of a nonlinear neutral stochastic fractional differential system. We prove the …

In this work, the controllability result of a class of fractional evolution nonlocal impulsive
quasilinear delay integro-differential systems in a Banach space has been established by …

In this article, we deal with the controllability for a class of the fractional integro-differential
equations with infinite delay and non-instantaneous impulses. Our findings are derived by …

In this manuscript, we deal with the nonlocal controllability results for the fractional evolution
system of 1< r< 2 1<r<2 in a Banach space. The main results of this article are tested by …

The paper is concerned with the controllability of fractional functional evolution equations of
Sobolev type in Banach spaces. With the help of two new characteristic solution operators …

In this paper, we establish two sufficient conditions for nonlocal controllability for fractional
evolution systems. Since there is no compactness of characteristic solution operators, our …

The paper is concerned with the complete controllability of fractional evolution systems
without involving the compactness of characteristic solution operators introduced by us. The …

In this article, we study some existence and controllability results for two classes of second
order functional differential equations with delay and random effects. To begin, we employ a …

This typescript explores the existence and uniqueness of solutions for Riemann–Liouville
neutral stochastic fractional differential equations with both retarded and advanced …

The review was devoted to describing the dynamics of various systems and control
processes in terms of the fractional integro-differential calculus. Consideration was given to …
