On a binary operation for positive operators

Shigeru Furuichi, Hamid Reza Moradi, Cristian Conde +1

M. Lin defined a binary operation for two positive semi-definite matrices in studying certain determinantal inequalities that arise from diffusion tensor imaging. This operation en…

Numerical Radius Bounds via the Euclidean Operator Radius and Norm

Mohammad Sababheh, Hamid Reza Moradi

In this paper, we begin by showing a new generalization of the celebrated Cauchy-Schwarz inequality for the inner product. Then, this generalization is used to present some bounds…

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…

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…
