Fanâ€™s minimax inequality is extended to the context of metric spaces with global nonpositive curvature. As a consequence, a much more general result on the existence of a Nash equilibrium isâ€¦ (More)

The fact that the time optimal controls for parabolic equations have the bang-bang property has been recently proved for controls distributed inside the considered domain (interior control). The mainâ€¦ (More)

We consider a finite difference semi-discrete scheme for the approximation of the boundary controls of a 1-D equation modelling the transversal vibrations of a hinged beam. It is known that, due toâ€¦ (More)

In this paper we consider a vibrational percussion system described by a one-dimensional hyperbolic partial differential equation with boundary dissipation at one extremity and a normal complianceâ€¦ (More)

In this paper we study, from a control theoretic view point, a 1D model of fluid-particle interaction. More precisely, we consider a point mass moving in a pipe filled with a fluid. The fluid isâ€¦ (More)

This article considers the linear 1-d SchrÃ¶dinger equation in (0, Ï€) perturbed by a vanishing viscosity term depending on a small parameter Îµ > 0. We study the boundary controllability properties ofâ€¦ (More)
