Right $\ell$-groups associated with von Neumann algebras

Quantum Algebra 2020-01-31 v2 Operator Algebras

Abstract

In [Rum18], Rump defined and characterized noncommutative universal groups G(X)G(X) for generalized orthomodular lattices XX. We give an explicit construction of G(X)G(X) in terms of \emph{pure paraunitary groups} when XX is the projection lattice of a von Neumann algebra. The results given here extend some of those in [Die19].
