A Note On The Stahl’s Theorem
Let $\\mathcal{H}$ be a Hilbert space and $\\mathbb{B}(\\mathcal{H})$ denotes the algebra of all bounded linear operators on $\\mathcal{H}$ and $A$ be a bounden operator in $\\mathcal{H}$. Let $A,B\\in\\mathbb{B}(\\mathcal{H})$ ...
Some results on Kwong functions and related inequalities
We investigate some relations between Kwong functions and operator monotone functions. As an application, we present an arithmetic–geometric mean type inequality by showing that for two continuous functions f, g on (0,∞)(0,∞) such that View...
Estimates of operator convex and operator monotone functions on bounded intervals
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 such behavior not only for operator monotone functions but also...
More on operator monotone and operator convex functions of several variables
$ is a $k$ variables operator convex function of order $(n_1,\\ldots,n_k)$ such that $m=n_1 n_2\\ldots n_k$. Also, if $f$ is an operator monotone function of order $n^{k+1}$, then $\\phi$ is a $k$ variables operator monotone function of order $n...
A note on some preservation results on the Laplace transform ordering of residual lives
In this paper, we provide several preservation results for Laplace transform ordering of residual lives (Lt-rl) under
the reliability operations convolutions, mixtures and series systems. We also show that this order ...
Operator means and positivity of block operators
The aim of this paper is to find some sufficient conditions for positivity of block matrices of positive operators.
It is shown that for positive operators $A,B,C$ and for every non-negative operator monotone function $f$ on $
(0...
More on operator monotone functions
We investigate some properties of operator monotone functions. In particular,
we show that if f is a non-constant operator monotone function on an interval
J and A;B are self-adjoint operators with spectra in J such that A > B, then...

A New Class of Operator Monotone Functions via Operator Means
In this paper, we obtain a new class of functions, which is developed via the Hermite--Hadamard inequality for convex functions. The well-known one-one correspondence between the class of operator monotone functions and operator connections declares...
Operator Ky Fan type inequalities
)$ is an operator monotone function with $f (1) = 1$, $f'(1)=\\mu$, and associated mean $\\sigma$, then for all operators $A$ and $B$ on a complex Hilbert space $\\mathscr{H}$ such that $0<A,B\\leq\\frac{1}{2}I$, we have...
