This study concentrates on the analysis of a stochastic SIC epidemic system with an
enhanced and general perturbation. Given the intricacy of some impulses caused by …

In this article, a fractal-fractional order tuberculosis mathematical model is presented for the
existence results, numerical simulations and stability analysis. The model has six classes S …

In the current manuscript, we deal with the dynamics of a piecewise covid-19 mathematical
model with quarantine class and vaccination using SEIQR epidemic model. For this, we …

The ongoing study deals with various forms of solutions for the biological population model
with a novel beta-time derivative operators. This model is very conducive to explain the …

In this work, we propose an age‐structured prey–predator model with infection developed in
the prey population. Our main goal is to distinguish the effect of the predator maturation …

In this research, we investigate an SVIR system with distributed delay. We first provide some
preliminary results on the proprieties of the Volterra function and the well-posedness of the …

In this article, deterministic and fractional properties of the epidemic model for rabies
considered with convex incidence rate are discussed. The dynamics are studied without …

In this paper, a five-compartment model is used to explore the dynamics of the COVID-19
pandemic, taking the vaccination campaign into account. The present model consists of five …

A discrete-time predator–prey model is investigated in this paper. In considered model, the
population is assumed to follow the model suggested by Ricker 1954. Existence and stability …

In this research, we are interested in discussing the evolution of the COVID-19 infection
cases and predicting the spread of COVID-19 disease in Algeria and India. To this aim, we …
