E-semigroups and product systems of W-bimodules
Yusuke Sawada
Product systems have been originally introduced to classify E-semigroups on type I factors by Arveson. We develop the classification theory of E-semigroups on a general von…
The affine property of quasi-free states on self-dual CAR algebras
Yusuke Sawada
We study conditions for which the correspondence between quasi-free states on self-dual CAR algebras and covariant operators is affine.
Notes on the bicategory of W*-bimodules
Yusuke Sawada, Shigeru Yamagami
Categories of W*-bimodules are shown in an explicit and algebraic way to constitute an involutive W*-bicategory.
A remark on the minimal dilation of the semigroup generated by a normal UCP-map
Yusuke Sawada
There are known three ways to construct the minimal dilation of the discrete semigroup generated by a normal unital completely positive map on a von Neumann algebra, which are give…
