Two types of commutator inequalities for the Hilbert-Schmidt norm are established. The first type of these inequalities is related to a classical inequality of Clarkson, and the second type is related to the unitary approximation of positive and invertible operators. 2002 Elsevier Science (USA)

Let A, B, and X be n × n complex matrices such that A and B are positive semidefinite.

In this letter we discuss a new entanglement measure. It is based on the Hilbert-Schmidt norm of operators. We give an explicit formula for calculating the entanglement of a large set of states on C 2 m C 2 . Furthermore we find some relations between the entanglement of relative entropy and the Hil
We show that a certain matrix norm ratio studied by Parlett has a supremum that is O(&) when the chosen norm is the Frobenius norm, while it is O(1og n) for the 2-norm. This ratio arises in Parlett's analysis of the Cholesky decomposition of an n by n matrix.
This paper gives some necessary and sufficient conditions for the weighted Cesaro mean operators to be bounded on Herz spaces.
