On the Euclidean operator radius and norm
Mohammad Sababheh, Hamid Reza Moradi, Mohammad Alomari
In this paper, we show several bounds for the numerical radius of a Hilbert space operator in terms of the Euclidean operator norm. The obtained forms will enable us to find intere…
A convex-block approach for numerical radius inequalities
Mohammad Sababheh, Cristian Conde, Hamid Reza Moradi
This article implements a simple convex approach and block techniques to obtain several new refined versions of numerical radius inequalities for Hilbert space operators. This incl…
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…
Improvements of the weighted Hermite-Hadamard inequality and applications to mean inequality
Shigeru Furuichi, Nicuşor Minculete, Hamid Reza Moradi
This paper aims to characterize the function appearing in the weighted Hermite-Hadamard inequality. We provide improved inequalities for the weighted means as applications of the o…
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…
