Existence and upper semicontinuity of global attractors for neural fields in an unbounded domain

Electronic Journal of Differential Equations, 2010
In this article, we prove the existence and upper semicontinuity of compact global attractors for the flow of the equation $$ frac{partial u(x,t)}{partial t}=-u(x,t)+ J*(fcirc u)(x,t)+ h, quad h > 0, $$ in $L^{2}$ weighted spaces.

Upper semicontinuity of uniform attractors for singular perturbed second order nonautonomous delay lattice systems

Electronic Journal of Differential Equations
In this article, we consider the upper semicontinuity of the uniform attractors for the singular perturbed second order nonautonomous delay lattice systems driven by the almost periodic forces as the coefficient of second order derivative term tends to ...

Private Information: Similarity as Compatibility [PDF]

We investigate the continuity of equilibrium in differential information economies with a finite number of agents. In this setting, agents can make contingent contracts based on events that are commonly observed.

Attractors for Damped Semilinear Wave Equations with Singularly Perturbed Acoustic Boundary Conditions

, 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 ...

Uniform Attractor for the Partly Dissipative Nonautonomous Lattice Systems

Advances in Difference Equations, 2009
The existence of uniform attractor in l2×l2 is proved for the partly dissipative nonautonomous lattice systems with a new class of external terms belonging to Lloc2(R,l2), which are locally asymptotic smallness and translation bounded but not ...

Upper semicontinuity of random attractors for non-compact random dynamical systems

Electronic Journal of Differential Equations, 2009
The upper semicontinuity of random attractors for non-compact random dynamical systems is proved when the union of all perturbed random attractors is precompact with probability one.

Pullback attractors for a class of non-Newtonian micropolar fluids

Electronic Journal of Differential Equations, 2018
In this article we study the long time behavior of the two-dimensional flow for non-Newtonian micropolar fluids in bounded smooth domains, in the sense of pullback attractors.

Limiting dynamics for stochastic complex Ginzburg-Landau systems with time-varying delays on unbounded thin domains

Demonstratio Mathematica
This study deals with the limiting dynamics for stochastic complex Ginzburg-Landau systems with time-varying delays and multiplicative noise on unbounded thin domains. We first prove the existence and uniqueness of pullback tempered random attractors for
