Fuglede-Putnam type theorems via the Aluthge transform
Let $A=U|A|$ and $B=V|B|$ be the polar decompositions of $A\\\\in
\\\\mathbb{B}(\\\\mathscr{H}_1)$ and $B\\\\in \\\\mathbb{B}(\\\\mathscr{H}_2)$ and
let $\\\\mbox{Com}(A,B)$ stand for the set of operators
Advanced refinements of Young and Heinz inequalities
In this article, we prove several multi-term refinements of Young type inequalities for both real numbers and operators improving several known results. Among other results, we prove that for all $0\\leq \\nu\\leq 1$ and ...
Schatten p-norm inequalities related to an extended operator parallelogram law
Let mathcal{C}_p be the Schatten p -class for p>0 .
Generalizations of the parallelogram law for the Schatten 2 -norms have been given in the following form:
If mathbf{A}= {A_1,A_2, ldots,A_n } and ...
Numerical radius inequalities for products of Hilbert space operators
An investigation of unitarily invariant norm inequalities of Lowner--Heinz type
We utilize some $2 \\times 2$ matrix tricks to obtain several unitarily invariant norm inequalities corresponding to the L\\"{o}wner--Heinz inequality, the arithmetic--geometric mean inequality and the Corach--Porta--Recht inequality...
Characterization of a generalized triangle inequality in normed spaces
For a normed linear space (X, | cdot |) and p>0 we characterize all
n -tuples ( mu_1, cdots, mu_n) in mathbb{R}^{n} for which the
generalized triangle inequality of the second type
|x_1+ ...
Landau and Gruss type inequalities for inner product type integral transformers in norm ideals
For a probability measure mu and for square integrable fields
( mathscr{A}_t) and ( mathscr{B}_t) ( t\\\\in\\\\Omega ) of commuting
normal operators we prove Landau type inequality

Norm inequalities related to the Heron and Heinz means
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 ...
Quadratic interpolation of the Heinz means
The main goal of this article is to present several quadratic refinements and reverses of the well known Heinz inequality, for numbers and matrices, where the refining term is a quadratic function in the mean parameters. ...
Jensen inequalities for P-class functions
In this paper, we first give some characterizations for P-class functions. Then
giving a Hermite–Hadamard type inequality for P-class functions, we prove equivalency of
some significant metrics in normed ...
