Integro-differential equations with delays: A perturbation approach
Hamid Bounit, Abderrahim Driouich, Said Hadd
This paper focuses on the study of integro-differential equations with delays, presenting a novel perturbation approach. The primary objective is to introduce the concepts of class…
On nonlinear Miyadera-Voigt perturbations
Mohamed Fkirine, Said Hadd
Let be linear operators on a Banach space such that generates a strongly continuous semigroup on , and be a globally Lipschitz fun…
Feedback theory approach to positivity and stability of evolution equations
Abed Boulouz, Hamid Bounit, Said Hadd
In this paper, we study the positivity and (uniform) exponential stability of a large class of perturbed semigroups. Our approach is essentially based on the feedback theory of inf…
Staffans-Weiss perturbations for Maximal -regularity in Banach spaces
A. Amansag, H. Bounit, A. Driouich +1
In this paper we show that the concept of maximal -regularity is stable under a large class of unbounded perturbations, namely Staffans-Weiss perturbations. To that purpose, w…
On the maximal regularity for a class of Volterra integro-differential equations
A. Amansag, H. Bounit, A. Driouich +1
We propose an approach based on perturbation theory to establish maximal -regularity for a class of integro-differential equations. As the left shift semigroup is involved for…
On norm continuity, differentiability and compactness of perturbed semigroups
A. Boulouz, H. Bounit, A. Driouich +1
The main purpose of this paper is to treat semigroups properties, like norm continuity, compactness and differentiability for perturbed semigroups in Banach spaces. In particular,…
Maximal -regularity for perturbed evolution equations in Banach spaces
A. Amansag, H. Bounit, A. Driouich +1
The main purpose of this paper is to investigate the concept of maximal -regularity for perturbed evolution equations in Banach spaces. We mainly consider three classes of per…
