Introduction Mathematical modelling is a rapidly expanding field that offers new and
interesting opportunities for both mathematicians and biologists. Concerning COVID-19, this …

In the given manuscript, the fractional mathematical model for the current pandemic of
COVID-19 is investigated. The model is composed of four agents of susceptible (S) …

In this mathematical research paper, we analyze in detail the basic SIQR epidemic model.
We calculate its reproductive value R 0, equilibrium points and analyze the stability of the …

In this manuscript, we investigate a nonlinear SIQR pandemic model to study the behavior of
covid-19 infectious diseases. The susceptible, infected, quarantine and recovered classes …

In this work, we will introduce two novel positivity preserving operator splitting nonstandard
finite difference (NSFD) schemes for the numerical solution of SEIR reaction diffusion …

Malaria importation is one of the hypothetical drivers of malaria transmission dynamics
across the globe. Several studies on malaria importation focused on the effect of the use of …

The terms susceptibility, exposure, infectiousness, and recovered all have some inherent
ambiguity because different population members have different susceptibility levels …

In this work, we numerically investigate a three-dimensional nonlinear reaction-diffusion
susceptible-infected-recovered hepatitis B epidemic model. To that end, the stability and …

In this article, a susceptible, infectious, and recovered (SIR) model with fuzzy parameters is
discussed. These concepts are uncertain due to the different degrees of susceptibility …

The main purpose of this paper is to investigate the solution of general reaction–diffusion
glycolysis system numerically. Glycolysis model demonstrates the positive solution as the …
