On the admissibility of observation operators in the context of maximal regularity

Omar El Mennaoui, Said Hadd, Yassine Kharou

We study admissible observation operators for perturbed evolution equations using the concept of maximal regularity. We first show the invariance of the maximal $L^{p}$ -regularity un…

On nonlinear Miyadera-Voigt perturbations

Mohamed Fkirine, Said Hadd

Let $A, C, P : D (A) \subset X \to X$ be linear operators on a Banach space $X$ such that $- A$ generates a strongly continuous semigroup on $X$ , and $F : X \to X$ be a globally Lipschitz fun…
