Operator mean inequalities and Kwong functions
Nahid Gharakhanlu, Mohammad Sal Moslehian, Hamed Najafi
In this paper, we study operator mean inequalities for the weighted arithmetic, geometric and harmonic means. We give a slight modification of Audenaert's result to show the relati…
Operator maps of Jensen-type
Frank Hansen, Mohammad Sal Moslehian, Hamed Najafi
Let denote the set of self-adjoint operators acting on a Hilbert space with spectra contained in an open interval . A map $Φ\colon\mathb…
Estimates of operator convex and operator monotone functions on bounded intervals
M. Fujii, M. S. Moslehian, H. Najafi +1
Recently the behavior of operator monotone functions on unbounded intervals with respect to the relation of strictly positivity has been investigated. In this paper we deeply study…
An extension of the Lowner-Heinz inequality
Mohammad Sal Moslehian, Hamed Najafi
We extend the celebrated Löwner--Heinz inequality by showing that if are Hilbert space operators such that , then A^r - B^r \geq ||A||^r-(||A||- \frac{1}{||(A-…
Around Operator Monotone Functions
M. S. Moslehian, H. Najafi
We show that the symmetrized product of two positive operators and is positive if and only if for all non-negative operator monotone function…
