Structure and bifurcation of pullback attractors in a non-autonomous Chafee-Infante equation [PDF]
, 2011 The Chafee-Infante equation is one of the canonical infinite-dimensional dynamical systems for which a complete description of the global attractor is available.

Nonautonomous Discrete Neuron Model with Multiple Periodic and Eventually Periodic Solutions
Discrete Dynamics in Nature and Society, 2015 We introduce a nonautonomous discrete neuron model based on the Rulkov map and investigate its dynamics. Using both the linear stability and bifurcation analyses of the system of piecewise difference equations, we determine dynamical bifurcations and ...

The Study of Identification Method for Dynamic Behavior of High-Dimensional Nonlinear System
Shock and Vibration, 2019 The dynamic behavior of nonlinear systems can be concluded as chaos, periodicity, and the motion between chaos and periodicity; therefore, the key to study the nonlinear system is identifying dynamic behavior considering the different values of the ...

Journal of Mathematics, 2023 The SIRDV (Susceptible, Infected, Recovered, Death, Vaccinated) compartmental model along with time-varying parameters is used to model the spread of COVID-19 in the United States. Time-varying parameters account for changes in transmission rates, people’

Sensitive dependence for nonautonomous discrete dynamical systems [PDF]
, 2018 Given a nonautonomous discrete dynamical system (NDS) we show that transitivity and density of periodic points do not imply sensitivity in general, i.e., in the definition of Devaney chaos there are no redundant conditions for NDS.

A Billingsley type theorem for Bowen topological entropy of nonautonomous dynamical systems
Open Mathematics, 2022 This article is devoted to the study of the Bowen topological entropy for nonautonomous dynamical systems, which is an extension of the classical definition of Bowen topological entropy. We show that the Bowen topological entropy can be determined by the

Synchronization of dissipative dynamical systems driven by non-Gaussian Lévy noises
, 2010 Dynamical systems driven by Gaussian noises have been considered extensively in modeling, simulation, and theory. However, complex systems in engineering and science are often subject to non-Gaussian fluctuations or uncertainties.

Dynamical behavior of a general non-autonomous dynamical system
Applied General TopologyIn this work, we investigate dynamical notions such as minimality, almost periodicity, equicontinuity, transitivity, proximality and periodicity for a general non-autonomous dynamical system.
