Background and objective: Hepatitis virus infections are affecting millions of people
worldwide, causing death, disability, and considerable expenditure. Chronic infection with …

The present paper investigates the critical normal form coefficients for the one-parameter
and two-parameter bifurcations of a discrete-time Bazykin–Berezovskaya prey-predator …

In this paper, a novel type of generalized Kopel triopoly model is presented to reveal the
complex dynamics and transitions between different dynamic behaviors. First, based on …

A newly disclosed nonstandard finite difference method has been used to discretize a Lotka–
Volterra model to investigate the critical normal form coefficients of bifurcations for both one …

The refuge effect is critical in ecosystems for stabilizing predator-prey interactions. The
purpose of this research was to investigate the complexities of a discrete-time predator-prey …

In this paper, we consider the constructive equations of the fractional second-grade fluid.
The considered fluid model is described by the Caputo derivative. The problem consists to …

This study investigates the dynamics of a discrete-time prey-predator model with a
harvesting effect on the predator. During the analysis of the bifurcations at the interior fixed …

Chemical kinetics is a branch of chemistry that investigates the rates of chemical reactions
and has applications in cosmology, geology, and physiology. In this study, we develop a …

Experimental studies have reported the dependence of nitric oxide (NO) on the regulation of
neuronal calcium ([Ca2+]) dynamics in neurons. But, there is no model available to estimate …

Formulating suitable dynamical models to describe the interplay of different chemical
substance in biology and chemistry is a very interesting topic. In this article, we set up a new …
