Complex Dynamics of Intelligence‐Level Adjustment in Intelligent and Connected Vehicle Manufacturers
Against the backdrop of software monetization and carbon constraints reshaping competition, it is necessary to identify the stability boundary for intelligence adjustment. We build a heterogeneous duopoly of fuel‐vehicle (FV) and new‐energy‐vehicle (NEV) firms that jointly choose output and intelligence each period, where intelligence shifts effective ...

This study investigates a discrete‐time predator–prey model that includes both prey refuge and memory effects. The research identifies the conditions under which fixed points exist and remain stable. A key focus is placed on analyzing different types of bifurcation—such as period doubling (PD), Neimark–Sacker (NS), and strong resonances (1 : 2, 1 : 3 ...

Neimark-Sacker bifurcation in a discrete dynamical model of population genetics [PDF]
In this paper we investigate a genetic model initiated by Gábor Tusnády. This model is a four-dimensional system of difference equations which describes the change of distribution of genotypes from generation to generation in the case of one locus and ...

A dynamic model of a green supply chain, comprising two manufacturers incorporating green technology innovation and one product component supplier, was constructed based on a gradient adjustment mechanism. The dynamic behavior of the system was analyzed through stability analysis of equilibrium points and bifurcation conditions, using parameter ...

Dynamical analysis of discretized Logistic model with Caputo- Fabrizio fractional derivative [PDF]
In this paper we consider a fractional order Logistic model with Caputo-Fabrizio fractional derivative. By applying two-step Adams-Bashforth scheme, we obtain a system of difference equations.

The Complex Dynamics of Automobile Manufacturer Competition Model on Video Platforms
Video platforms have significantly broadened the marketing and advertising channels available to automobile manufacturers, leading to reduced transaction costs and increased profits for participants. Through building a dynamic automobile manufacturer competition model with bounded rationality, we have revealed the following conclusions: Adjustment ...

The existence of Neimark-Sacker bifurcation on a discrete-time SIS-Epidemic model incorporating logistic growth and allee effect [PDF]
This article investigates the dynamical properties of a discrete time SIS-Epidemic model incorporating logistic growth rate and Allee effect. The forward Euler discretization method is employed to obtain the discrete-time model. All possible fixed points

Dynamics and Bifurcations in a Two‐Species Ricker Competition Model With Nonmonotonic Growth
This study investigates the dynamics of a discrete‐time competition model involving two species with nonmonotonic growth rates. The system is formulated through coupled Ricker‐type equations that incorporate both intraspecific and interspecific interactions.

Estudo da bifurcação de Neimark-Sacker [PDF]
This dissertation deals with a local bifurcation for planar smooth mappings, depending on a real parameter, called Neimark-Sacker bifurcation of codimension 1, which, in a certain sense, shares many similarities with the Hopf bifurcation for ordinary ...
