This paper deals with the approximate controllability of a class of non-instantaneous
impulsive hybrid systems for fractional differential inclusions under Hilfer derivative of order …

This paper is concerned with a class of stochastic impulsive evolution system with the
fractional substantial derivative of the order α∈(1, 2). We introduce the fractional substantial …

In this article, we study the Finite-Time Stability (FTS) of Linear Stochastic Fractional
Differential Equations of Itô-Doob Type with Delay (LSFDEIDTwD) for a derivative order …

The primary focus of this manuscript is on the approximate controllability of second-order
semilinear control systems with impulses. There have been two sets of necessary …

In this paper, we investigate the general solution of a new quadratic functional equation of
the form∑ 1≤ i< j< k≤ r ϕ li+ lj+ lk= r− 2∑ i= 1, i≠ jr ϕ li+ lj+− r 2+ 3 r− 2/2∑ i= 1 r ϕ li. We …

In this paper, we analyse the approximate controllability of Hilfer fractional stochastic
differential systems of order 1< μ< 2 in Hilbert spaces. The primary findings are carried out …

In the present work, we have established sufficient conditions for boundary controllability of
nonlocal fractional neutral integrodifferential evolution systems with time-varying delays in …

In this study, we primarily employ the principle of contraction mapping to establish the
approximate controllability and existence of optimal control for a multi-delay stochastic …

This paper presents a survey for some recent research on the controllability of nonlinear
fractional evolution systems (FESs) in Banach spaces. The prime focus is exact …

In this paper, we discuss the approximate controllability for mixed type non-autonomous
fractional differential equations. By using the Schauder fixed point theorem and two …
