Attractors for an Energy‐Damped Viscoelastic Plate Equation

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 14, Page 13864-13881, 30 September 2025.
ABSTRACT In this paper, we consider a class of non‐autonomous beam/plate equations with an integro‐differential damping given by a possibly degenerate memory and an energy damping given by a nonlocal ε$$ \varepsilon $$‐perturbed coefficient. For each ε>0$$ \varepsilon >0 $$, we show that the dynamical system generated by the weak solutions of the ...

Nonautonomous attractors of skew-product flows with digitized driving systems

open access: yesElectronic Journal of Differential Equations, 2001
The upper semicontinuity and continuity properties of pullback attractors for nonautonomous differential equations are investigated when the driving system of the generated skew-product flow is digitized.

Polyhedral Convexity and the Existence of Approximate Equilibria in Discontinuous Games [PDF]

open access: yes
Radzik (1991) showed that two-player games on compact intervals of the real line have " { equilibria for all " > 0, provided that payo® functions are upper semicontinuous and strongly quasi-concave.

The porous medium equation: Large deviations and gradient flow with degenerate and unbounded diffusion

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 9, Page 1609-1655, September 2025.
Abstract The problem of deriving a gradient flow structure for the porous medium equation which is thermodynamic, in that it arises from the large deviations of some microscopic particle system is studied. To this end, a rescaled zero‐range process with jump rate g(k)=kα,α>1$g(k)=k^\alpha, \alpha >1$ is considered, and its hydrodynamic limit and ...

Upper semicontinuity of the attractor for lattice dynamical systems of partly dissipative reaction diffusion systems

open access: yesJournal of Applied Mathematics, 2005
We investigate the existence of a global attractor and its upper semicontinuity for the infinite-dimensional lattice dynamical system of a partly dissipative reaction diffusion system in the Hilbert space l2×l2.

Attractors and global averaging of non-autonomous reaction-diffusion equations in R^n

open access: yes, 2002
We consider a family of non-autonomous reaction-diffusion equations with almost periodic, rapidly oscillating principal part and nonlinear interactions.

Semicontinuity of the Solution Mapping to a Parametric Generalized Weak Ky Fan Inequality

open access: yesAbstract and Applied Analysis, 2014
Under new assumptions, which do not contain any information about the solution set, the upper and lower semicontinuity of the solution mapping to a class of parametric generalized weak Ky Fan inequality are established by using a nonlinear scalarization ...

UPPER SEMICONTINUITY OF PULLBACK ATTRACTORS FOR MULTI-VALUED RANDOM COCYCLE

open access: yesThe Journal of Applied Analysis and Computation, 2019
In this paper we study the upper semicontinuity of random attractors for multi-valued random cocycle when small random perturbations approach zero or small perturbation for random cocycle is considered.

Existence and continuity of global attractors for a degenerate semilinear parabolic equation

open access: yesElectronic Journal of Differential Equations, 2009
In this article, we study the existence and the upper semicontinuity with respect to the nonlinearity and the shape of the domain of global attractors for a semilinear degenerate parabolic equation involving the Grushin operator.
