Global attractors of evolutionary systems [PDF]

open access: yesJournal of Dynamics and Differential Equations, 2006
An abstract framework for studying the asymptotic behavior of a dissipative evolutionary system $\mathcal{E}$ with respect to weak and strong topologies was introduced in [8] primarily to study the long-time behavior of the 3D Navier-Stokes equations ...

Attractors for damped semilinear wave equations with singularly perturbed acoustic boundary conditions

open access: yesElectronic Journal of Differential Equations, 2018
Under consideration is the damped semilinear wave equation $$ u_{tt}+u_t-\Delta u+u+f(u)=0 $$ in a bounded domain $\Omega$ in $\mathbb{R}^3$ subject to an acoustic boundary condition with a singular perturbation, which we term "massless acoustic ...

An operator methodology for the global dynamic analysis of stochastic nonlinear systems

open access: yesTheoretical and Applied Mechanics Letters, 2023
In a global dynamic analysis, the coexisting attractors and their basins are the main tools to understand the system behavior and safety. However, both basins and attractors can be drastically influenced by uncertainties.

Average Process of Fractional Navier–Stokes Equations with Singularly Oscillating Force

open access: yesFractal and Fractional, 2022
The averaging process between two-dimensional fractional Navier–Stokes equations driven by a singularly oscillating external force and the averaged equations corresponding to the limiting case are investigated.

The Construction of Global Attractors [PDF]

open access: yesProceedings of the American Mathematical Society, 1990
The purpose of this note is to show that every inverse limit space of an interval mapping can be realized as a global attractor for a homeomorphism of the plane.

Compact global attractors of discrete inclusions [PDF]

open access: yesNonlinear Analysis: Theory, Methods & Applications, 2006
The aim of this paper is the study of the existence of compact global attractors of discrete inclusions and control systems. More precisely, on the metric space \(W\), the authors consider a discrete inclusion \(u_{t+1}\in F(u_t)\), associated with \({\mathfrak M}:= \{f_j,j\in J\}\), where \(F(u)= \{f(u)\mid f\in{\mathfrak M}\}\) for all \(u\in W ...

Quasi-stability and continuity of attractors for nonlinear system of wave equations

open access: yesNonautonomous Dynamical Systems, 2021
In this paper, we study the long-time behavior of a nonlinear coupled system of wave equations with damping terms and subjected to small perturbations of autonomous external forces.

On the Residual Continuity of Global Attractors

open access: yesMathematics, 2022
In this brief paper, we studied the residual continuity of global attractors Aλ in varying parameters λ∈Λ with Λ a bounded Borel set in Rd. We first reviewed the well-known residual continuity result of global attractors and then showed that this ...

Compact Global Attractors

open access: yes, 2020
The second chapter of this book is dedicated to the study of different kinds of dissipativity for dynamical systems (both autonomous and nonautonomous): point, compact, local, bounded, and weak. Criteria for point, compact, and local dissipativity are given.

Trajectory attractors method for dissipative partial differential equations with small parameter [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
The purpose of this work is to study the limit behaviour of trajectory attractors for some equations and systems from mathematical physics depending on a small parameter when this small parameter approaches zero.
