In this article, we mainly focus on the existence and approximate controllability results for the
fractional semilinear impulsive control system of order r∈(1, 2). We consider two different …

In this paper, we investigate the approximate controllability for fractional integrodifferential
inclusions of order r∈(1, 2) in Banach space with sectorial operators. In particular, we obtain …

In this paper, a new mathematical model for dual variants of COVID-19 and HIV co-infection
is presented and analyzed. The existence and uniqueness of the solution of the proposed …

This work analyzes the existence and partial-approximate controllability of non-local semi-
linear systems involving two Riemann-Liouville fractional derivatives without Lipschitz …

This manuscript concerns the approximate controllability results in Hilbert space of Hilfer
fractional differential inclusions. We show that the Hilfer fractional neutral differential …

Fractional differential equations are used in many areas, such as the fields of science. In this
paper, we study existence results for a class of fractional mixed Volterra-Fredholm-type …

The main motivation of our conversation is the approximate controllability of fractional
stochastic Sobolev‐type Volterra–Fredholm integro‐differential equation of order 1< r< 2 …

The main concern of this manuscript is to study the optimal control problem for Hilfer
fractional neutral stochastic integrodifferential systems with infinite delay. Initially, we …

In this work, we offer a set of appropriate conditions for the approximate controllability of
second‐order impulsive neutral stochastic integro‐differential evolution inclusions with …

In this paper, we establish a qualitative theory for implicit fractional order differential
equations (IFODEs) with nonlocal initial condition (NIC) with delay term. Because area …
