A spectral inequality for degenerated operators and applications
Rémi Buffe,Kim Dang Phung +1 more
TL;DR: In this article, a Lebeau-Robbiano spectral inequality for a degenerated one-dimensional elliptic operator was established for finite time stabilisation of a parabolic equation.

Observation estimate for the heat equations with Neumann boundary condition via logarithmic convexity
Rémi Buffe,Kim Dang Phung +1 more
TL;DR: In this article, an inequality of Holder type traducing the unique continuation property at one time for the heat equation with a potential and Neumann boundary condition was proved for the case of the potential condition, and the main feature was to overcome the propagation of smallness by a global approach using a refined parabolic frequency function method.

Control and exponential stability for a transmission problem of a viscoelastic wave equation
TL;DR: In this paper, the energy decay of a viscoelastic wave in an heterogeneous medium with a memory term located in one of the medium has been studied under geometrical and analytical hypothesis on the memory term.

Controllability of a simplified fluid-structure interaction system
Rémi Buffe,Takéo Takahashi +1 more
TL;DR: In this article, the controllability of a fluid-structure interaction system where the fluid is viscous and incompressible and where the structure is elastic and located on a part of the boundary of the fluid's domain is studied.
A Carleman estimate in the neighborhood of a multi-interface and applications to control theory
Rémi Buffe
- 07 Feb 2018
TL;DR: In this paper, a Carleman estimate in a neighborhood of a multi-interface, that is, near a point where n manifolds intersect, under compatibility assumptions between the weight, the operators at the multiple interfaces, and the elliptic operators in the interior and the usual sub-ellipticity condition is obtained.
