We study the gain of regularity for the initial value problem for acoupled nonlinear Schrödinger system that describes some physical phenomena such as the propagation in birefringent optical fibers, Kerr-like photo refractive media in optics and Bos

We study in this paper the well-posedness and stability of three structures with interfacial slip and two infinite memories effective on the transverse displacement and the rotation angle. We consider a large class of kernels and prove that the syste

In this work, we study the effect of the positions of the dissipative mechanisms on a bar of three components; two of them formed by viscous materials of Kelvin Voight type. The difference is that ...

In this work, we consider a one-dimensional model of a thermoviscoelastic mixture with second sound. Under suitable assumption on the constitutive constants of the system, we prove, using the theory of semigroup of linear operators and results obtain

In this paper we consider the dissipative Bresse system with an attached hollow-tip body that contains granular material, the resulting model being called hybrid system. Our main result is to show that the corresponding model is not exponentially sta

In this paper we consider the transmission problem of a material composed of three components; one of them is a Kelvin--Voigt viscoelastic material, the second is an elastic material (no dissipation), and the third is an elastic material inserted wit

Localized frictional damping was studied by several authors in one or more space dimension, (see e.g. [5],[10], [19], [20], [27], [26]). The main result of the above articles is that localized frictional damping producesexponential decay in time of t

In this paper we investigate the asymptotic behavior of solutions to the initial boundary value problem for a mixture of two rigid solids modeling temperature and porosity. Our main result is to establish conditions which ensure the analyticity and t

Using Bourgain spaces and the generator of dilation P=3t ∂ t +x ∂ x , which almost commutes with the linear Korteweg-de Vries operator, we show that a solution of the initial value problem associated for the coupled system of equations of Kortewe
