Switching Controls for Analytic Semigroups and Applications to Parabolic Systems
(SIAM, 2021-08-05)
In this work, we extend the analysis of the problem of switching controls proposedin [E. Zuazua,J. Eur. Math. Soc. (JEMS), 13 (2011), pp. 85--117]. The problem asks the followingquestion: Assuming that one can control a ...

On some geometric inverse problems for nonscalar elliptic systems
(Elsevier, 2020-07-02)
In this paper, we consider several geometric inverse problems for linear elliptic systems. We prove uniqueness and stability results. In particular, we show the way that the observation depends on the perturbations of the ...

On the uniform controllability for a family of non-viscous and viscous Burgers- α systems
(E.D.P. Sciences, 2021-06-24)
In this paper we study the global controllability of families of the so called non-viscous and viscous Burgers- systems by using boundary and space independent distributed controls. In these equations, the usual convective ...

Non null controllability of Stokes equations with memory
(EDP Sciences, 2020-09-30)
In this paper, we consider the null controllability problem for the Stokes equations with a memory term. For any positive final time T > 0, we construct initial conditions such that the null controllability does not hold ...

Observability inequalities on measurable sets for the stokes system and applications
(SIAM, 2020-07-29)
In this paper, we establish spectral inequalities on measurable sets of positiveLebesgue measure for the Stokes operator, as well as observability inequalities on space-time mea-surable sets of positive ...
