Exact boundary controllability of the linear Biharmonic Schrödinger equation with variable coefficients
Kaïs Ammari, Hedi Bouzidi
In this paper, we study the exact boundary controllability of the linear fourth-order Schrödinger equation, with variable physical parameters and clamped boundary conditions on a b…

Regularity of the semigroups associated with some damped coupled elastic systems II: a nondegenerate fractional damping case
Kaïs Ammari, Farhat Shel, Louis Tebou
In this paper, we examine regularity issues for two damped abstract elastic systems; the damping and coupling involve fractional powers , with , of the pri…

Regularity and stability of the semigroup associated with some interacting elastic systems I: A degenerate damping case
K. Ammari, F. Shel, L. Tebou
In this paper, we examine regularity and stability issues for two damped abstract elastic systems. The damping involves the average velocity and a fractional power , with in…
