Minimal E0–semigroups
It is known that every semigroup of normal completely positive maps of a von Neumann can be “dilated” in a particular way to an E0-semigroup acting on a larger von Neumann algebra. The E0-semigroup is not uniquely determined by the completely positive semigroup; however, it is unique (up to conjugacy) provided that certain conditions of minimality are met. Minimality is a subtle property, and i...
متن کاملContinuous Families of E0-semigroups
We consider families of E0-semigroups continuously parametrized by a compact Hausdorff space, which are cocycle-equivalent to a given E0-semigroup β. When the gauge group of β is a Lie group, we establish a correspondence between such families and principal bundles whose structure group is the gauge group of β. Let H be a Hilbert space, which we will always assume to be separable and infinitedi...
متن کاملZDD-Based Cryptanalysis of E0 Keystream Generator
BDD is an efficient data structure that in last few years has been used effectively in computer science and engineering. BDD-based attack in key stream cryptanalysis is supposed to be one of the best forms of attack in its kind. In this paper, we propose a new key stream attack which is based on ZDD(a variant of BDD). We show how our ZDD-based key stream attack can be used against the E0 type o...
متن کاملE0-dilation of strongly commuting CP0-semigroups
We prove that every strongly commuting pair of CP0-semigroups has a minimal E0-dilation. This is achieved in two major steps, interesting in themselves: 1: we show that a strongly commuting pair of CP0semigroups can be represented via a two parameter product system representation; 2: we prove that every fully coisometric product system representation has a fully coisometric, isometric dilation....
متن کاملOn the Existence of E0-semigroups
Product systems are the classifying structures for semigroups of endomorphisms of B(H), in that two E0-semigroups are cocycle conjugate iff their product systems are isomorphic. Thus it is important to know that every abstract product system is associated with an E0-semigrouop. This was first proved more than fifteen years ago by rather indirect methods. Recently, Skeide has given a more direct...
