Fractional calculus is particularly useful for describing the behavior of complex physical
systems. Many natural phenomena exhibit nonlocal characteristics, meaning that their …

Prey–predator models play a vital role in mathematical biology. The competition that evolves
between them is addressed in a broad scenario. According to genetics theory, various …

In this paper, we focus on exploring a mathematical model that captures the dynamics of
Corona Virus Disease (COVID-19), particularly emphasizing the influence of quarantine …

This study explores a nonautonomous model of prey-predator dynamics, featuring
continuous distributed delay and diffusion, with time-dependent parameters. Our model …

We propose a population dynamical model for SARS-CoV-2 that takes into account mask
compliance and effectiveness, in the context of saturated treatment. This model also …

In this study, we introduce and investigate the SEIQRD COVID-19 model incorporating Allee
and fear effects. Employing the next-generation matrix method, we derive the basic …

The COVID-19 pandemic continues to pose significant challenges to global public health,
necessitating the development of effective vaccination strategies to mitigate disease …

In this paper, an SIRS model with age structure is proposed for recurrent infectious diseases
by incorporating infectious delay and temporary immunity delay. Analysis shows that the …

The study employs sensitivity analysis and optimal control algorithms to understand the
dynamics of COVID-19 comprehensively. It assesses the stability of equilibrium points and …

In this research paper the identification and large implementation of a powerful SARS-CoV-2
vaccine may prevent considerable illnesses and fatalities from COVID-19 while minimizing …
