E $_{0}$ -semigroups and product systems of W $^{*}$ -bimodules

Yusuke Sawada

Product systems have been originally introduced to classify E $_{0}$ -semigroups on type I factors by Arveson. We develop the classification theory of E $_{0}$ -semigroups on a general von…

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.
