An extension of a Liapunov approach to the stabilization of second order coupled systems
T. Horsin, M. A. Jendoubi
This paper deals with the convergence to 0 of the energy of the solutions of a second order linear coupled system. In order to obtain the energy decay, we exhibit a Liapunov functi…
Lagrangian controllability at low Reynolds number
O. Glass, T. Horsin
In this paper, we establish a result of Lagrangian controllability for a fluid at low Reynolds number, driven by the stationary Stokes equation. This amounts to the possibility of…
Lagrangian controllability of inviscid perfect fluids: a constructive approach
T. Horsin, O. Kavian
We present here a constructive method of Lagrangian approximate control- lability for the Euler equation. We emphasize on different options that could be used for numerical recipes…
Optime L2-Control Problem In Coefficients For A Linea Elliptic Equation. II. Approximation Of Solutions And Optimality Conditions
Thierry Horsin, Peter Kogut, Olivier Wilk
In this paper we study we study a Dirichlet optimal control prob- lem associated with a linear elliptic equation the coefficients of which we take as controls in the class of integ…
