On an operator inequality [PDF]
\textit{F. Hansen} [Proc. Am. Math. Soc. 125, No. 7, 2093-2102 (1997; Zbl 0870.47013)] gave a characterization of operator convex functions in terms of Jensen's operator inequality. Following investigations by \textit{S. Friedland} and \textit{M. Katz} [Linear Algebra Appl. 85, 185-190 (1987; Zbl 0612.15010)], the author presents a simple proof of this

Operator iteration on the Young inequality [PDF]
In this paper, we employ iteration on operator version of the famous Young inequality and obtain more arithmetic-geometric mean inequalities and the reverse versions for positive operators.

Strong Converse Inequality for a Spherical Operator [PDF]
In the paper titled as "Jackson-type inequality on the sphere" (2004), Ditzian introduced a spherical nonconvolution operator , which played an important role in the proof of the well-known Jackson inequality for spherical harmonics.

Approximation of an Additive ϱ1,ϱ2-Random Operator Inequality [PDF]
We solve the additive ϱ1,ϱ2-random operator inequality ξtTω,u+v−Tω,u−Tω,v≥κMξtϱ1Tω,u+v+Tω,u−v−2Tω,u,ξtϱ22Tω,u+v/2−Tω,u−Tω,v, in which ϱ1,ϱ2∈ℂ are fixed and max2ϱ1 ...

An Operator Extension of Čebyšev Inequality [PDF]
Some operator inequalities for synchronous functions that are related to the čebyšev inequality are given. Among other inequalities for synchronous functions it is shown that ∥ø(f(A)g(A)) - ø(f(A))ø(g(A))∥ ≤ max{║ø(f2(A)) - ø2(f(A))║, ║ø)G2(A)) - ø2(g(A))

Hölder’s inequality for shifted quantum integral operator [PDF]
We show by two counterexamples that Hölder’s inequality for shifted quantum integral operator does not hold in general and we prove the case in which it is valid.

Operator Arithmetic-Harmonic Mean Inequality on Krein Spaces [PDF]
We prove an operator arithmetic-harmonic mean type inequality in Krein space setting, by using some block matrix techniques of indefinite type. We also give an example which shows that the operator arithmetic-geometric-harmonic mean inequality for two

A variational inequality for the derivative of the scalar play operator [PDF]
We show that the directional derivative of the scalar play operator is the unique solution of a certain variational inequality. Due to the nature of the discontinuities involved, the variational inequality has an integral form based on the Kurzweil ...
