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 ...

Exponential Potentials and Attractor Solution of Dilatonic Cosmology [PDF]

open access: greenInternational Journal of Theoretical Physics, 2007
We present the scalar-tensor gravitational theory with an exponential potential in which pauli metric is regarded as the physical space-time metric. We show that it is essentially equivalent to coupled quintessence(CQ) model. However for baryotropic fluid being radiation there are in fact no coupling between dilatonic scalar field and radiation.

A robust family of exponential attractors for a time semi-discretization of the Ginzburg-Landau equation

open access: yesAIMS Mathematics, 2022
We consider a time semidiscretization of the Ginzburg-Landau equation by the backward Euler scheme. For each time step τ, we build an exponential attractor of the dynamical system associated to the scheme.

Exponential approach to the hydrodynamic attractor in Yang-Mills kinetic theory [PDF]

open access: yesPhysical Review D, 2022
We use principal component analysis to study the hydrodynamic attractor in Yang-Mills kinetic theory undergoing the Bjorken expansion with Color Glass Condensate initial conditions.

Global and exponential attractors for the Penrose-Fife system [PDF]

open access: greenMathematical Models and Methods in Applied Sciences, 2008
The Penrose–Fife system for phase transitions is addressed. Dirichlet boundary conditions for the temperature are assumed. Existence of global and exponential attractors is proved. Differently from preceding contributions, here the energy balance equation is both singular at 0 and degenerate at ∞.

A conserved Caginalp phase-field system with two temperatures and a nonlinear coupling term based on heat conduction

open access: yesAIMS Mathematics, 2023
Our aim in this paper is to study generalizations of the Caginalp phase-field system based on a thermomechanical theory involving two temperatures and a nonlinear coupling. In particular, we prove well-posedness results. More precisely, the existence and

Random exponential attractor for stochastic discrete long wave-short wave resonance equation with multiplicative white noise

open access: yesDiscrete & Continuous Dynamical Systems - B, 2020
We mainly consider the existence of a random exponential attractor (positive invariant compact measurable set with finite fractal dimension and attracting orbits exponentially) for stochastic discrete long wave-short wave resonance equation driven by ...
