Biomathematics has become one of the most significant areas of research as a result of
interdisciplinary study. Chronic diseases sometimes referred to as non-communicable and …

In this paper, a novel two-stage epidemic model with a dynamic control strategy is proposed
to describe the spread of Corona Virus Disease 2019 (COVID-19) in China. Combined with …

In this paper, we consider a modified SIR (susceptible-infected-recovered/removed) model
that describes the evolution in time of the infectious disease caused by Sars-Cov-2 (Severe …

COVID-19 is a novel coronavirus affecting all the world since December last year. Up to
date, the spread of the outbreak continues to complicate our lives, and therefore, several …

In this paper, we investigate novel solutions of fractional‐order option pricing models and
their fundamental mathematical analyses. The main novelties of the paper are the analysis …

In this study, a novel reaction–diffusion model for the spread of the new coronavirus (COVID-
19) is investigated. The model is a spatial extension of the recent COVID-19 SEIR model …

Fractional calculus is a 300 years topic, which has been introduced to real physics systems
modeling and engineering applications. In the last few decades, fractional-order nonlinear …

This paper presents and investigates a new fractional discrete COVID-19 model which
involves three variables: the new daily cases, additional severe cases and deaths. Here, we …

We investigate, through a fractional mathematical model, the effects of physical distance on
the SARS-CoV-2 virus transmission. Two controls are considered in our model for …

We propose a Caputo-based fractional compartmental model for the dynamics of the novel
COVID-19 pandemic. The newly proposed nonlinear fractional order model is an extension …
