The COVID-19 infection which is still infecting many individuals around the world and at the
same time the recovered individuals after the recovery are infecting again. This reinfection of …

In this paper, we consider a mathematical model to explain, understanding, and to forecast
the outbreaks of COVID-19 in India. The model has four components leading to a system of …

In this article, we presents the theoretical and numerical study of the four dimensional
chaotic system which has no equilibrium point in the sense of fractal-fractional Mittag–Leffler …

In this paper, we propose a fractional-order COVID-19 epidemic model with a quarantine
and standard incidence rate using the Caputo fractional-order derivative. The model …

Recent research has shown that ideal capacitors and inductors do not physically exist, and
that the dynamics of real devices can be accurately described by fractional-order (FO) …

The transmission of influenza has been explained by analyzing a diffusive epidemic model.
The Operating splitting based on finite difference (OSBFD), explicit formula based on …

In this paper, we investigate the stochastic nature of the COVID-19 temporal dynamics by
generating a fractional-order dynamic model and a fractional-order-stochastic model …

Abstract Coronavirus disease 2019 (CoViD-19) is an infectious disease caused by severe
acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Among many symptoms, cough …

We discuss the dynamics of new COVID-19 epidemic model by considering asymptomatic
infections and the policies such as quarantine, protection (adherence to health protocols) …

Mass-media coverage is one of the most widely used government strategies on influencing
public opinion in times of crisis. Awareness campaigns are highly influential tools to expand …
