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.

Adjoints of Generalized Composition Operators with Linear Fractional Symbol

Extracta Mathematicae, 2016
Given a positive integer n and φ : U → U, an analytic self-map of the open unit disc in the complex plane, the generalized composition operator Cφ(n) is defined by Cφ(n)f = f (n) ◦ φ for f belonging to some Hilbert space of analytic functions on U.

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.
