Further Properties of PPT and Hyponormal Matrices
Hamid Reza Moradi, Ibrahim Halil Gümüş, Mohammad Sababheh
This paper discusses further properties of positive partial transpose matrices, with applications towards hyponormal, semi-hyponormal, and -normal matrices. The obtained res…
New Orders Among Hilbert Space Operators
Mohammad Sababheh, Hamid Reza Moradi
This article introduces several new relations among related Hilbert space operators. In particular, we prove some Löewner partial orderings among $T, |T|, \mathcal{R}T, \mathcal{I}…
Generalized Euclidean Operator Radius
Mohammad W. Alomari, Mohammad Sababheh, Cristian Conde +1
In this paper, we introduce the operator radius of Hilbert space operators as a generalization of the Euclidean operator radius and the operator radius. Properties of the n…
Further Properties of Accretive Matrices
Hamid Reza Moradi, Shigeru Furuichi, Mohammad Sababheh
To better understand the algebra of all complex matrices, we explore the class of accretive matrices. This class has received renowned attention in rece…
Norm and numerical radius inequalities for operator matrices
Fuad Kittaneh, Hamid Reza Moradi, Mohammad Sababheh
Operator matrices have played a significant role in studying Hilbert space operators. In this paper, we discuss further properties of operator matrices and present new estimates fo…
Further numerical radius inequalities
Mohammad Sababheh, Cristian Conde, Hamid Reza Moradi
In this article, we present some new inequalities for the numerical radius of products of Hilbert space operators and the generalized Aluthge transform. In particular, we show some…
