Research on Stability and Bifurcation for Two-Dimensional Two-Parameter Squared Discrete Dynamical Systems

Mathematics
This study investigates a class of two-dimensional, two-parameter squared discrete dynamical systems. It determines the conditions for local stability at the fixed points for these proposed systems.

Analysis of a Mathematical Model of Marital Satisfaction

Mathematical Methods in the Applied Sciences, Volume 49, Issue 7, Page 6143-6157, 15 May 2026.
ABSTRACT A large number of marriages end in divorce. In this paper, we present a model for the emotional state of a couple based on bilinear ordinary differential equations. We study the effect of changes of each individual's self‐emotional state on the couple's state.

Dynamical Behavior of a Modified Leslie–Gower One Prey–Two Predators with Competition

Mathematics, 2020
We study the dynamics of a modified Leslie–Gower one prey–two predators model with competition between predator populations. The model describes complex dynamics in the permanence, global stability and bifurcation.

Bioenergetic trophic trade‐offs determine mass‐dependent extinction thresholds across the Cenozoic

Ecology, Volume 107, Issue 5, May 2026.
Abstract Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We develop a bioenergetic, three‐level trophic framework—typical of terrestrial mammalian ecosystems—to explore how bioenergetic trade‐offs emerging

A nonautonomous transcritical bifurcation problem with an application to quasi-periodic bubbles

Discrete and Continuous Dynamical Systems, 2003
In this interesting paper, the authors study the phenomenon of stability breakdown for nonautonomous ordinary differential equations whose time dependence is determined by a strictly ergodic flow. More precisely, an approach for a nonautonomous version of the classical transcritical bifurcation is provided.

Mathematical Modeling of Forest Biomass Dynamics: A Focus on Seedling Contribution in Case of Wonsho Woreda (Kileye and Gishere), Sidama Regional State, Ethiopia

Natural Resource Modeling, Volume 39, Issue 1, February 2026.
ABSTRACT In this study, we introduce a mathematical ecology model that describes the interactions among forest biomass, the human population, various development activities, and seedlings. The study applies modified Leslie‐Gower and Holling type II functional responses to capture these interactions.

A Survey of SIR‐Based Differential Epidemic Models for Control and Security Against Malware Propagation in Computer Networks

SECURITY AND PRIVACY, Volume 9, Issue 1, January/February 2026.
ABSTRACT Unarguably, malware and their variants have metamorphosed into objects of attack and cyber warfare. These issues have directed research focus to modeling infrastructural settings and infection scenarios, analyzing propagation mechanisms, and conducting studies that highlight optimized remedial measures.

Bifurcation Behavior Analysis in a Predator-Prey Model

Discrete Dynamics in Nature and Society, 2016
A predator-prey model is studied mathematically and numerically. The aim is to explore how some key factors influence dynamic evolutionary mechanism of steady conversion and bifurcation behavior in predator-prey model.

Bifurcations and Structures of the Parameter Space of a Discrete-Time SIS Epidemic Model

Journal of Mathematics, 2022
The dynamics of a discrete-time SIS epidemic model are reported in this paper. Three types of codimension one bifurcation, namely, transcritical, flip, Neimark–Sacker (N-S) bifurcations, and their intersection codimension two bifurcations including 1 : 2,

Mathematical Modeling of the Dynamics of Female Genital Schistosomiasis as a Risk Factor to Cervical Cancer

Abstract and Applied Analysis, Volume 2026, Issue 1, 2026.
Female genital schistosomiasis (FGS), caused by chronic infection with Schistosoma haematobium, represents a significant but neglected gynecological condition that affects approximately 56 million women in sub‐Saharan Africa. This parasitic disease manifests itself through chronic inflammation and tissue damage in the female genital tract, leading to ...
