Stability of an inverse problem for the discrete wave equation and convergence results
Lucie Baudouin, Sylvain Ervedoza, Axel Osses
Using uniform global Carleman estimates for discrete elliptic and semi-discrete hyperbolic equations, we study Lipschitz and logarithmic stability for the inverse problem of recove…
Transmutation techniques and observability for time-discrete approximation schemes of conservative systems
Sylvain Ervedoza, Enrique Zuazua
In this article, we consider abstract linear conservative systems and their time-discrete counterparts. Our main result is a representation formula expressing solutions of the cont…
Long-time behavior for the two-dimensional motion of a disk in a viscous fluid
Sylvain Ervedoza, Matthieu Hillairet, Christophe Lacave
In this article, we study the long-time behavior of solutions of the two-dimensional fluid-rigid disk problem. The motion of the fluid is modeled by the two-dimensional Navier-Stok…
