Finite-time stabilization via impulse control of degenerate singular parabolic equations

Walid Zouhair, Ghita El Guermai, Ilham Ouelddris

This paper examines the impulse controllability of degenerate singular parabolic equations through a modern framework focused on finite-time stabilization. Furthermore, we provide…

Intrinsic Ultracontractivity for a class of Schroedinger Semigroups in $L^{2} (R^{n})$ using Log-Sobolev-inequalities and duality arguments

Christoph Schwerdt, Ilham Ouelddris

We present a class of potentials $q : R^{n} \to (0, \infty)$ that implies the weighted SchrÃ¶dinger semigroup $I ¨ ^{- 1} e^{- t H} I ¨ $ to map a weighted Lebesgue fu…
