New versions of refinements and reverses of Young-type inequalities with the Kantorovich constant

open access: yesSpecial Matrices, 2023
Recently, some Young-type inequalities have been promoted. The purpose of this article is to give further refinements and reverses to them with Kantorovich constants.

Bell's inequality with Dirac particles [PDF]

open access: yes, 2012
We study Bell's inequality using the Bell states constructed from four component Dirac spinors. Spin operator is related to the Pauli-Lubanski pseudo vector which is relativistic invariant operator.

Some inequalities for operator monotone functions

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2022
In this paper we show that, if that the function f : [0, ∞) → 𝔾 is operator monotone in [0, ∞) then there exist b ≥ 0 and a positive measure m on [0, ∞) such that [f(B)-f(A)](B-A)==b(B-A)2+∫0∞s2[∫01[((1-t)A+tB+s)-1(B-A)]2dt]dm(s)\matrix{ {\left[ {f ...

INEQUALITIES CONCERNING B-OPERATORS

open access: yesIssues of Analysis, 2016
Summary: Let \(\mathcal{P}_{n}\) be the class of polynomials of degree at most \(n\). Rahman introduced the class \(\mathcal {B}_{n}\) of operators \(B\) that map \(\mathcal {P}_{n}\) into itself. In this paper we prove some results concerning such operators and thereby obtain generalizations of some well known polynomial inequalities.

A Grüss type operator inequality [PDF]

open access: yesAnnals of Functional Analysis, 2017
In [P. Renaud, "A matrix formulation of Gr\"uss inequality", Linear Algebra Appl. 335 (2001), 95--100] it was proved an operator inequality involving the usual trace functional. In this article, we give a refinement of such result and we answer positively the Renaud's open problem.

Estimates for Tsallis relative operator entropy [PDF]

open access: yes, 2017
We give the tight bounds of Tsallis relative operator entropy by using Hermite-Hadamard's inequality. Some reverse inequalities related to Young inequalities are also given.

An operator inequality

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
An inequality is proved in abstract separable Hilbert space H where A and B are bounded self-adjoint positive operators defined in H such that R(A)=R(B) and R(A) is closed.

Correlation Inequalities for Schrödinger Operators [PDF]

open access: yesMathematical Physics, Analysis and Geometry, 2020
This paper analyzes Sch dinger operators from viewpoint of correlation inequalities. We construct Griffiths inequalities for the ground state expectations by applying operator-theoretic correlation inequalities. As an example of such an application, we analyze the momentum distribution, i.e., the Fourier transform of the ground state density.

Norm inequalities related to the Heron and Heinz means [PDF]

open access: yes, 2017
In this article, we present several inequalities treating operator means and the Cauchy-Schwarz inequality. In particular, we present some new comparisons between operator Heron and Heinz means, several generalizations of the difference version of the ...

Some operator inequalities via convexity [PDF]

open access: yesLinear and Multilinear Algebra, 2021
In this article, we employ a standard convex argument to obtain new and refined inequalities related to the matrix mean of two accretive matrices, the numerical radius and the Tsallis relative operator entropy.
