We study the uniform decay of the total energy of solutions for a system in magnetoelasticity with localized damping near infinity in an exterior 3-D domain. Using appropriate multipliers and recent work by Charao and Ikekata [3], we conclude that th

We present a result on "simultaneous" exact controllability for two models that describe two hyperbolic dynamics. One is the system of Maxwell equations and the other a vector-wave equation with a pressure term. We obtain the main result using modifi

We study the asymptotic behavior in time of the solutions of a system of nonlinear Klein-Gordon equations. We have two basic results: First, in the L∞(ℝ3) norm, solutions decay like 0(t−3/2) as t→+∞ provided the initial data are sufficientl

We study the best possible energy decay rates for a class of linear second-order dissipative evolution equations in a Hilbert space. The models we consider are generated by a positive selfadjoint operator A A having a bounded inverse. Our discussion

We consider a linear coupled system of quasi-electrostatic equations which govern the evolution of a 3-D layered piezoelectric body. Assuming that a dissipative effect is effective at the boundary, we study the uniform stabilization problem. We prove

We study the resonances (or sattering frequenaes) associated with the syutem of elastic wave equations in an unbounded region Ω which is the union of a (bounded) cavity C, an (unbounded) exterior E and a thin channel Z conneding C with E. We show th

We consider the dynamical von Kármán equations for viscoelastic plates under the presence of a long-range memory. We find uniform rates of decay (in time) of the energy, provided that suitable assumptions on the relaxation functions are given. Name

New results on the validity of the so-called unique continuation property (UCP) for two nonlinear dispersive equations are given. We show that the UCP holds for the Benjamin-Bona-Mahony equation and Boussinesq's equation. Our strategy in both cases r
