Schmidt states and positivity of linear maps

, 2005
Using pure entangled Schmidt states, we show that m-positivity of a map is bounded by the ranks of its negative Kraus matrices. We also give an algebraic condition for a map to be m-positive. We interpret these results in the context of positive maps as entanglement witnesses, and find that only 1-positive maps are needed for testing entanglement.

On positive vectors in indefinite inner product spaces

Bulletin of Mathematical Sciences
Let [Formula: see text] be a linear space equipped with an indefinite inner product [Formula: see text]. Denote by [Formula: see text] the nonlinear set of positive vectors in [Formula: see text]. We demonstrate that the properties of a linear operator W

Operator quadratic mean and positive linear maps

Journal of Mathematical Inequalities
Summary: This paper presents several bounds for unital positive linear mappings and the socalled quadratic mean. Some of these results can be viewed as sub-multiplicative inequalities, while others are Cauchy-Schwarz-type inequalities. Related results that treat the tensor products will be presented, too.
