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…
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…
Spectral decomposition and Gelfand's theorem
A. Driouich, O. El-Mennaoui, M. Jazar
In this paper we are interested in spectral decomposition of an unbounded operator with discrete spectrum. We show that if generates a polynomially bounded -times integrated…
