Uncertainty relations for generalized metric adjusted skew information and generalized metric adjusted correlation measure

, 2013
In this paper, we give a Heisenberg-type or a Schrödinger-type uncertainty relation for generalized metric adjusted skew information or generalized metric adjusted correlation measure.

Numerical radius inequalities associated with the Cartesian decomposition

, 2015
We give several sharp numerical radius inequalities associated with the Cartesian decomposition of a Hilbert space operator A = B + iC . Among other inequalities, it is shown that 1 2 ‖ |B| + |C|‖ wr(A) ‖ |B| + |C|‖ for 0 < r 2 , where w(·) and ...

Noncommutative Chebyshev inequality involving the Hadamard product

, 2018
We present several operator extensions of the Chebyshev inequality for Hilbert space operators. The main version deals with the synchronous Hadamard property for Hilbert space operators.

Improved reverse arithmetic-geometric means inequalities for positive operators on Hilbert space

, 2015
In this paper, employing induction on the given reverse Young inequalities, we obtain more reverse arithmetic-geometric means inequalities for two positive operators.

Scalar approximants of quadratic operators with applications

, 2018
Among other results, we find the best scalar approximant of a quadratic operator with respect to the numerical radius and the operator norm. We use these results to give estimates for the numerical radii of products and commutators of quadratic operators.
