Weyl's Theorem for Bounded Self-Adjoint Operators

Hatem Baloudi, Mohamed Ali Dbeibia, Kamel Mahfoudhi

Let be a bounded self-adjoint operator on a separable infinite-dimensional right quaternionic Hilbert space, and let $\sigdS(T)$ be the set of right eigenvalues of finite type.…

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…

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…
