Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 11630-11651, August 2025.ABSTRACT This study examines the complex dynamics of dengue transmission by incorporating time delay into a comprehensive model. The model is designed to capture several essential components, including steady‐state events, immune waning, recuperation from infection, and partial shielding in human populations.

一类时滞计算机网络病毒模型的动力学行为(Dynamics of an epidemic model of computer virus with delays)
Zhejiang Daxue xuebao. Lixue ban, 2015 An SLBRS computer virus model with two delays is considered. Local stability and local Hopf bifurcation of this model are investigated. Sufficient conditions for local stability and the existence of local Hopf bifurcation are obtained by regarding ...

Stability of singular Hopf bifurcations
Journal of Differential Equations, 2004 Consider the singularly perturbed system \[ \frac{dx}{dt}=\varepsilon f(x,y,\lambda),\quad\frac{dy}{dt}= g(x,y,\lambda)\tag{*} \] with \(x\in\mathbb{R}^n\), \(y\in\mathbb{R}^m\), \(\varepsilon,\lambda\in\mathbb{R}\), \(\varepsilon\) small. It is assumed that there exists a curve \(\lambda=\lambda(\varepsilon)\) in the parameter plane associated with ...

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12011-12037, August 2025.ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.

Andronov-Hopf bifurcation with and without parameter in a cubic memristor oscillator with a line of equilibria. [PDF]
Chaos, 2017 The model of a memristor-based oscillator with cubic nonlinearity is studied. The considered system has infinitely many equilibrium points, which build a line of equilibria in the phase space.

Individuals Strategies and Predator–Prey Game Models in Deterministic and Random Settings
Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12587-12607, August 2025.ABSTRACT The authors propose a new predator–prey game model by integrating two optional strategies into prey species: cooperative and isolation strategies. An investigation of the evolutionary impact on predator–prey system dynamics is given. The model utilizes a replicator equation to track changes in the frequency of cooperative strategy among preys,

Transition from rotating waves to modulated rotating waves on the sphere
, 2005 We study non-resonant and resonant Hopf bifurcation of a rotating wave in SO(3)-equivariant reaction-diffusion systems on a sphere. We obtained reduced differential equations on so(3), the characterization of modulated rotating waves obtained by Hopf ...
