This paper is concerned with the Ulam-Hyers stability (UHs) of Caputo type fuzzy fractional
differential equations (FFDEs) with time-delays. By applying Schauder's fixed point theorem …

Our fundamental purpose in the present manuscript is to explore existence and uniqueness
criteria for a new coupled Caputo conformable system of pantograph problems in which for …

This paper considers the stability of a fractional differential equation with multi-point
boundary conditions and non-instantaneous integral impulse. Some sufficient conditions for …

In this manuscript, a qualitative analysis of the mathematical model of novel coronavirus
(COVID-19) involving anew devised fractal-fractional operator in the Caputo sense having …

This article is devoted to study a compartmental mathematical model for the transmission
dynamics of the novel Coronavirus-19 under Caputo fractional order derivative. By using …

This paper studies quasi-projective synchronization (QPS) and complete synchronization
(CS) for a class of fractional-order complex-valued neural networks with time delays by …

We explore a new kind of Caputo-type fractional fuzzy stochastic differential equations
(FFSDEs) with delay. We establish the existence result of FFSDEs with delay by monotone …

The present paper describes a three compartment mathematical model to study the
transmission of the current infection due to the novel coronavirus (2019-nCoV or COVID-19) …

Most exiting results for impulsive switched systems (ISSs) are mainly built on the
synchronous switching and impulses case; however, the impulses can not only occur in …

This paper deals with existence, uniqueness, and Hyers–Ulam stability of solutions to a
nonlinear coupled implicit switched singular fractional differential system involving Laplace …
