Integral Representations and Sharp Numerical Radius Inequalities for Hilbert Space Operators
Wasim Audeh, Fuad Kittaneh, Hamid Reza Moradi
We study the numerical radius \(ω(T)\) of a bounded linear operator \(T\) on a complex Hilbert space. Write \(T=A+iB\), where \(A\) and \(B\) are the real and imaginary parts of \(…
The -Cartesian Numerical Radii of Hilbert Space Operators
Wasim Audeh, Fuad Kittaneh, Hamid Reza Moradi +1
Let be a complex Hilbert space, and let be the Cartesian decomposition of , where and . We introduce the $L^…
A new collection of tuple operator inequalities
Zameddin I. Ismailov, Pembe Ipek Al, Hamid Reza Moradi +1
In this paper, we present several new bounds for the norm and numerical radius of sums of Hilbert space operators. The obtained bounds form a new collection that enriches our under…
Integral Numerical Radius and Operator Matrix Bounds
Shiva Sheybani, Hamid Reza Moradi, Mohammad Sababheh
We establish new integral inequalities for the numerical radius and the operator norm of bounded linear operators on Hilbert spaces. Our results refine classical triangle-type and…
More inner product bounds with applications
Mohammad Sababheh, Hamid Reza Moradi
The main goal of this paper is to present new bounds for certain inner products in Hilbert spaces, with applications to the numerical radius and the operator norm. The obtained res…
Some inequalities for adjointable operators on Hilbert -modules
Mohammad Sababheh, Hamid Reza Moradi, Qingxiang Xu +1
The main purpose of this paper is, in the general setting of the adjointable operators on Hilbert -modules, to develop two new tools that can be applied to deal with the posit…
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…
Further Subadditive Matrix Inequalities
I. H. Gumus, H. R. Moradi, M. Sababheh
Matrix inequalities that extend certain scalar ones have been at the center of numerous researchers' attention. In this article, we explore the celebrated subadditive inequality fo…
New inequalities for operator concave functions involving positive linear maps
S. Sheybani, M. E. Omidvar, H. R. Moradi
The purpose of this paper is to present some general inequalities for operator concave functions which include some known inequalities as a particular case. Among other things, we…
New Inequalities of the Kantorovich Type With Two Negative Parameters
S. Furuichi, H. R. Moradi
We show the following result: Let be two strictly positive operators such that and $m{\mathbf{1}_{\mathcal{H}}}\le B\le M{\ma…
On the Operator Jensen-Mercer Inequality
H. R. Moradi, S. Furuichi, M. Sababheh
Mercer inequality for convex functions is a variant of Jensen's inequality, with an operator version that is still valid without operator convexity. This paper is two folded. First…
Jensen operator inequality for strongly convex functions
H. R. Moradi, R. Naseri
We give a Jensen operator inequality for strongly convex functions. As a corollary, we improve operator Holder-McCarthy inequality under suitable conditions.
