Fractional powers of 3*3 block operators matrices: Application to PDES

Hatem Baloudi, Mohamed Ali Dbeibia, Aref Jeribi

In this paper, we investigate the fractional powers of block operator matrices, with a particular focus on their applications to partial differential equations (PDEs). We develop a…

Browder S-resolvent equation in quaternionic setting

H. Baloudi, A. Jeribi, H. Zmouli

This paper is devoted to the study of the S-eigenvalue of finite type of a bounded right quaternionic linear operator acting in a right quaternionic Hilbert space. The study is bas…

On existence theorems of a functional differential equations in partially ordered Banach algebras

Amor Fahem, Aref Jeribi, Najib Kaddachi

In this paper we are concerned with existence results for a coupled system of quadratic functional differential equations. This system is reduced to a fixed point problem for a blo…

Fixed point results for multivalued mapping with closed graphs in generalized Banach spaces

Khaled Ben Amara, Aref Jeribi, Najib Kaddachi +1

In this paper, by establishing a new characterization of the notion of upper semi-continuity of multi-valued mappings in generalized Banach spaces, we prove some Perov type fixed p…

Existence results for nonexpansive multi-valued operators and nonlinear integral inclusions

Khaled Ben Amara, Aref Jeribi, Najib Kaddachi

In this paper, we establish some new variants of fixed point theorems for a large class of countably nonexpansive multi-valued mappings. Some fixed point theorems for the sum and t…

Generalized form of fixed-point theorems in generalized Banach algebra relative to the weak topology with an application

Aref Jeribi, Najib Kaddachi, Zahra Laouar

In this paper, a general hybrid fixed point theorem for the contractive mappings in generalized Banach spaces is proved via measure of weak non-compactness and it is further applie…

Approximation of the fixed point of the product of two operators in Banach algebras with applications to some functional equations

Khaled Ben Amara, Maria Isabel Berenguer, Aref Jeribi

In this paper, the existence and uniqueness of the fixed point for the product of two nonlinear operator in Banach algebra is discussed. In addition, an approximation method of the…

Riesz projection and essential -spectrum in quaternionic setting

Hatem Baloudi, Sayda Belgacem, Aref Jeribi

This paper is devoted to the investigation of the Weyl and the essential spectrum of a bounded right quaternionic linear operator in a right quaternionic Hilbert space. Using t…

The adjacency matrix and the discrete Laplacian acting on forms

Hatem Baloudi, Sylvain Golenia, Aref Jeribi

We study the relationship between the adjacency matrix and the discrete Laplacian acting on 1-forms. We also prove that if the adjacency matrix is bounded from below it is not nece…
