Pullback attractor for a non-linear evolution equation in elasticity
(2014)
We prove the existence of a pullback attractor for a non{autonomous fourth order evolution equation arising in the fi eld of phase transitions and elasticity theory. The existence of several families of bounded absorbing ...

Fixed points and exponential stability for stochastic partial integro–differential equations with delays
(Research India Publications, 2014)
In this paper, we study the existence and asymptotic stability in the pth-moment of mild solutions of nonlinear impulsive stochastic partial functional integro-differential equations with delays. We suppose that the linear ...

On Differential Equations with Delay in Banach Spaces and Attractors for Retarded Lattice Dynamical Systems
(2014)
In this paper we first prove a rather general theorem about existence of solutions for an abstract differential equation in a Banach space by assuming that the nonlinear term is in some sense weakly continuous. We then ...

Stability of delay evolution equations with stochastic perturbations
(2014)
The investigation of stability for hereditary systems is often related to the construction of Lyapunov functionals. The general method of Lyapunov functionals construction, which was proposed by V.Kolmanovskii and L.Shaikhet, ...

Caracterización de los atractores en sistemas dinámicos no autónomos
(2014-03-21)
El estudio de los sistemas dinámicos es de gran importancia, ya que están relacionados con fenómenos del mundo real. Los problemas que consideraremos en este trabajo están, ante todo, motivados por la dinámica de las ...

Existence results fortime-dependent neutral functional integrodifferential equations driven by a fractional Brownian motion
(Euclidean Press, 2014)
This article presents some results on existence and uniqueness of mild solutions to neutral stochastic functional evolution integrodifferential equations driven by a fractional Brownian motion. The existence of mild solutions ...

Asymptotic Behaviour of a Non-Autonomous Lorenz-84 System
(2014)
The so called Lorenz-84 model has been used in climatological studies, for example by coupling it with a low-dimensional model for ocean dynamics. The behaviour of this model has been studied extensively since its introduction ...

Practical asymptotic stability of nonlinear stochastic evolution equations
(2014)
In this paper we establish some su cient conditions ensuring almost sure practical asymptotic stability with a non-exponential decay rate for solutions to stochastic evolution equations based on Lyapunov techniques.

Asymptotic Behaviour of a Logistic Lattice System
(2014)
In this paper we study the asymptotic behaviour of solutions of a lattice dynamical system of a logistic type. Namely, we study a system of in nite ordinary di erential equations which can be obtained after the spatial ...

Stability of stationary solutions to 2D-Navier-Stokes models with delays
(International Press, 2014)
In this paper we establish some sufficient conditions for the exponential stability of the stationary solution to a two-dimensional Navier-Stokes model with delay in the forcing term. We are able to cover several situation ...
