On a numerical construction of doubly stochastic matrices with prescribed eigenvalues
Kassem Rammal, Bassam Mourad, Hassan Abbas +1
We study the inverse eigenvalue problem for finding doubly stochastic matrices with specified eigenvalues. By making use of a combination of Dykstra's algorithm and an alternating…

H. A. Issa, B. Mourad, H. Abbass
Let be the -th symmetric tensor power of . In \cite{IAM}, we have expressed the normalized trace of as an integral of the -th power…
On an integral representation of the normalized trace of the -th symmetric tensor power of matrices and some applications
Hassan Issa, Hassan Abbas, Bassam Mourad
Let be an matrix and let be its -th symmetric tensor product. We express the normalized trace of as an integral of the -th powers of the…
New log-majorization results concerning eigenvalues and singular values and a complement of a norm inequality
Mohammad M. Ghabries, Hassane Abbas, Bassam Mourad +1
The purpose of this paper is to establish new log-majorization results concerning eigenvalues and singular values which generalize some previous work related to a conjecture and an…
Inequalities for the generalized numerical radius
H. Abbas, S. Harb, H. Issa
In the present paper, we provide several inequalities for the generalized numerical radius of operator matrices as introduced by A. Abu-omar and F. Kittaneh in [3]. We generalize t…
Formal Solutions of a Class of Pfaffian Systems in Two Variables
Moulay Barkatou, Suzy S. Maddah, Hassan Abbas
