Exact boundary control for the wave equation in a polyhedral time-dependent domain
(Elsevier B.V., 2014)
Exponential decay for Kirchhoff wave equation with nonlocal condition in a noncylindrical domain
(Elsevier B.V., 2004-06-01)
In this paper, we prove the exponential decay as time goes to infinity of regular solutions of the problem for the Kirchhoff wave equation with nonlocal condition and weak dampingu(tt) - M (\\delU\\(2)(2)) Deltau + ...
A note on the controllability for the wave equation in nonsmooth plane domains
(Elsevier B.V., 2006-01-01)
We study exact boundary controllability for a two-dimensional wave equation in a region which is an angular sector of a circle or an angular sector of an annular region. The control, of Neumann type, acts on the curved ...
On exact boundary controllability for linearly coupled wave equations
(Academic Press Inc. Elsevier B.V., 2011-09-15)
In this paper we study exact boundary controllability for a system of two linear wave equations coupled by lower order terms. We obtain square integrable control of Neuman type for initial state with finite energy, in ...

Nonlinear neumann boundary stabilization of the wave equation using rotated multipliers
(2010-04)
We study the boundary stabilization of the wave equation
by means of a linear or nonlinear Neumann feedback. The rotated
multiplier method leads to new geometrical cases concerning the active
part of the boundary where ...
