On the stability of a laminated Timoshenko problem with interfacial slip in the whole space under frictional dampings or infinite memories

open access: yesNonautonomous Dynamical Systems, 2020
The author of the present paper considered in [16] a model describing a vibrating strucure of an interfacial slip and consists of three coupled hyperbolic equations in one-dimensional bounded interval, where the dissipation is generated by either a ...

Three weak solutions for a Neumann elliptic equations involving the p→(x)\vec p\left( x \right)-Laplacian operator

open access: yesNonautonomous Dynamical Systems, 2020
The aim of this paper is to establish the existence of at least three weak solutions for the following elliptic Neumann problem {-Δp→(x)u+α(x)|u|p0(x)-2u=λf(x,u)inΩ,∑i=1N|∂u∂xi|pi(x)-2∂u∂xiγi=0on∂Ω,\left\{ {\matrix{ { - {\Delta _{\vec p\left( x \right)}}

Global Existence and Stability for Neutral Functional Evolution Equations with State-Dependent Delay

open access: yesNonautonomous Dynamical Systems, 2014
In this paper we prove the global existence and attractivity of mild solutions for neutral semilinear evolution equations with state-dependent delay in a Banach space.

Monotone Multivalued Nonautonomous Dynamical Systems

open access: yes
This paper is devoted to the study of nonautonomous multivalued semiflows and their associated pullback attractors. For this kind of dynamical systems we are able to characterize the upper and lower bounds of the attractor as complete trajectories belonging to the attractor, so that all the internal dynamics is confined in this region, which can be ...

Attractors for non-autonomous retarded lattice dynamical systems

open access: yesNonautonomous Dynamical Systems, 2015
In this paperwe study a non-autonomous lattice dynamical system with delay. Under rather general growth and dissipative conditions on the nonlinear term,we define a non-autonomous dynamical system and prove the existence of a pullback attractor for such ...

Dynamical analysis of a predator-prey interaction model with time delay and prey refuge

open access: yesNonautonomous Dynamical Systems, 2018
In this paper, we study a predator-prey model with prey refuge and delay. We investigate the combined role of prey refuge and delay on the dynamical behaviour of the delayed system by incorporating discrete type gestation delay of predator.

The reconstruction of an equation of visco-elasticity

open access: yesNonautonomous Dynamical Systems, 2018
We are concerned with the reconstruction of two coefficients of an integro-differential equation modeling the deformation of materials with memory.We show that we can explicitly reconstruct the memory, the source terms and the diffusion constant from two

Sensitivity of Fuzzy Nonautonomous Dynamical Systems

open access: yesEuropean Journal of Pure and Applied Mathematics, 2019
This paper is devoted to a study of relations between two forms of sensitivity of nonautonomous dynamical system and its induced fuzzy systems. More specially, we study strong sensitivity and mean sensitivity in an original nonautonomous system and its connections with the same ones in its induced system, including set-valued system and fuzzified ...
