Some Bifurcations of Codimensions 1 and 2 in a Discrete Predator–Prey Model with Non-Linear Harvesting

open access: yesMathematics
This paper delves into the dynamics of a discrete-time predator–prey system. Initially, it presents the existence and stability conditions of the fixed points.

An Algebraic Approach to Analyze an MSEIR Epidemic Model

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This study introduces a fully algorithmic framework for analyzing the dynamics of an MSEIR (Maternal, Susceptible, Exposed, Infectious, Recovered) epidemic model. Unlike traditional approaches that rely on heuristic, model‐specific Lyapunov functions for global stability or manual algebraic manipulations for finding equilibria, we employ computational ...

Bifurcations of a modified Leslie–Gower predator–prey model with fear, Allee effect and hunting cooperation strategy

open access: yesJournal of Biological Dynamics
The fear preoften leads to changes in the physiological characteristics of the prey. Different stages of prey exhibit different physiological behaviours, such as susceptibility to predator risk, which often leads to Allee effect.

Difference equations as models of evolutionary population dynamics

open access: yesJournal of Biological Dynamics, 2019
We describe the evolutionary game theoretic methodology for extending a difference equation population dynamic model in a way so as to account for the Darwinian evolution of model coefficients.

Stability and bifurcation analysis of two-species competitive model with Michaelis–Menten type harvesting in the first species

open access: yesAdvances in Difference Equations, 2020
In this paper, a two-species competitive model with Michaelis–Menten type harvesting in the first species is studied. We have made a detailed mathematical analysis of the model to describe some important results that may be produced by the interaction of

Mathematical Analysis of the Impact of Poverty and Unemployment on Crime Trends in Sub‐Saharan Countries

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
Crime remains a persistent global challenge with profound socioeconomic implications. This paper develops a deterministic mathematical model to analyze crime dynamics in sub‐Saharan Africa, specifically evaluating the impacts of poverty, unemployment, drug abuse, illiteracy, and socioeconomic inequality.

Bifurcations and chaos in a novel discrete economic system

open access: yesAdvances in Mechanical Engineering, 2019
In this article, a novel discrete system based on an economic model is introduced. Conditions for local stability of the model’s fixed points are obtained. Existence of supercritical Neimark–Sacker bifurcation is shown around the game’s Nash equilibrium.

Non-autonomous bifurcation in impulsive systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
This is the first paper which considers non-autonomous bifurcations in impulsive differential equations. Impulsive generalizations of the non-autonomous pitchfork and transcritical bifurcation are discussed. We consider scalar differential equation with

Complex Dynamics of a Predator–Prey System With Fear Effect in Prey

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This study investigates the dynamical consequences of predator‐induced fear in a predator–prey system by integrating nonlinear fear effects, intraspecific competition, and Holling type II predation. We analyze both continuous‐ and discrete‐time formulations to capture a wide spectrum of ecological dynamics.

Dynamical behaviors of a two-competitive metapopulation system with impulsive control

open access: yesAdvances in Difference Equations, 2017
In this paper, we study the dynamical behaviors of a two-competitive metapopulation system with impulsive control and focus on the stable coexistence of the superior and inferior species.
