Eventual Ideal Properties of the Riemann-Liouville Analytic Semigroup
Ihab Alam, Isabelle Chalendar, Fida El Chami +2
In this paper, we revisit the Riemann--Liouville analytic semigroup. In particular, we completely characterize the membership to the Schatten class on , as well as…

Biharmonic Steklov operator on differential forms
Fida El Chami, Nicolas Ginoux, Georges Habib +1
We introduce the biharmonic Steklov problem on differential forms by considering suitable boundary conditions. We characterize its smallest eigenvalue and prove elementary properti…

Rigidity results for spin manifolds with foliated boundary
Fida El Chami, Nicolas Ginoux, Georges Habib +1
In this paper, we consider a compact Riemannian manifold whose boundary is endowed with a Riemannian flow. Under a suitable curvature assumption depending on the O'Neill tensor of…
