Period-doubling and Neimark–Sacker bifurcations of plant–herbivore models [PDF]
Advances in Difference Equations, 2019 The interaction between plants and herbivores plays a vital role for understanding community dynamics and ecosystem function given that they are the critical link between primary production and food webs. This paper deals with the qualitative nature of two discrete-time plant–herbivore models. In both discrete-time models, function for plant-limitation

Exploring Ecological Dynamics and Bifurcation Structure of a Prey–Predator Model
Complexity, Volume 2026, Issue 1, 2026.The present work examines the dynamical features of a discrete‐time Rosenzweig–MacArthur predator–prey system in which the predation rate is modulated by prey density. Through a combination of theoretical derivations and computational experiments, we establish the occurrence of period‐doubling (PD) and Neimark–Sacker (NS) bifurcations, both of which ...

Complex Dynamics of Intelligence‐Level Adjustment in Intelligent and Connected Vehicle Manufacturers
Complexity, Volume 2026, Issue 1, 2026.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 ...

Complexity, Volume 2026, Issue 1, 2026.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 ...

Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.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 ...

The Complex Dynamics of Automobile Manufacturer Competition Model on Video Platforms
Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.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 ...

Dynamical analysis of discretized Logistic model with Caputo- Fabrizio fractional derivative [PDF]
Computational Ecology and Software, 2021 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.
