In this paper, we obtain a set of sufficient conditions to prove the approximate controllability
for a class of nonlocal neutral fractional integro-differential equations, with time varying …

We introduce the concepts of simultaneous finite dimensional exact and mean square
approximate controllability (finite-approximate controllability) in the framework of semilinear …

In this work, we study the approximate controllability for a class of neutral control systems
governed by semi‐linear neutral equations with infinite delay in Hilbert space. Sufficient …

In this paper, the approximate controllability of a class of fractional stochastic neutral integro-
differential inclusions with infinite delay in Hilbert spaces is considered. By using the Hölder …

In this paper, we investigate the controllability for a class of nonlocal second‐order impulsive
neutral stochastic integro‐differential equations with infinite delay in Hilbert spaces. More …

This paper is mainly concerned with the approximate controllability of fractional stochastic
integro-differential equations with infinite delay of order. Sufficient conditions for …

We study the approximate controllability of partial fractional neutral stochastic functional
integro-differential inclusions with state-dependent delay under the assumptions that the …

In the recent past, a number of research articles have explored the stability, existence, and
uniqueness of the solutions and controllability of dynamical systems with a fractional order …

This paper addressed the controllability of nonlinear fractional order integrodifferential
systems with input delay. Firstly, the Caputo fractional derivatives and the Mittag‐Leffler …

In this paper, we study the existence of mild solutions for nonlocal stochastic integro-
differential equations driven by fractional Brownian motions with Hurst parameter H> 1 2 …
