Dynamic analysis of a Leslie-Gower predator-prey model with the fear effect and nonlinear harvesting

open access: yesMathematical Biosciences and Engineering, 2023
In this paper, we investigate the stability and bifurcation of a Leslie-Gower predator-prey model with a fear effect and nonlinear harvesting. We discuss the existence and stability of equilibria, and show that the unique equilibrium is a cusp of ...

Global Structural Stability of a Saddle Node Bifurcation [PDF]

open access: yesTransactions of the American Mathematical Society, 1978
S. Newhouse, J. Palis, and F. Takens have recently proved the global structural stability of a one parameter unfolding of a saddle node when the nonwandering set is finite and transversality conditions are satisfied. (The diffeomorphism is Morse-Smale except for the saddle node.) Using their local unfolding of a saddle node and our method of compatible

The Effect of Electroosmosis on the Peristaltic Transport of Eyring Powell Fluid: Bifurcation Analysis of the Non‐Linear Dynamical System

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
The mathematical investigation aims to study the physiological flow inside the channel with an electric double layer (EDL) of zeta potential. The flow is assumed to be in a horizontal two‐dimensional channel containing Eyring Powell fluid like blood at a specific temperature.

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

open access: yesSECURITY 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.

Backward bifurcation and saddle-node bifurcation in virus-immune dynamics

open access: yes, 2021
Recently, Wang and Xu [ Appl. Math. Lett. 78 (2018) 105-111] studied thresholds and bi-stability in virus-immune dynamics. In this paper, we show there also exist backward bifurcation and saddle node bifurcation in this model. Our investigation demonstrates the existence of post-bifurcation phenomenon in the system when the immune strength was selected

The Dynamical Landscape of the Negative‐Order (3+1)‐Dimensional Calogero–Bogoyavlenskii–Schiff Equation

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
A new negative‐order form of the (3 + 1)‐dimensional Calogero–Bogoyavlenskii–Schiff equation is examined in this investigation. This equation plays an important role in accurately describing the thermodynamic properties of mixtures, particularly in chemical engineering applications.
