Isometries between non-commutative symmetric spaces associated with semi-finite von Neumann algebras
Pierre de Jager, Jurie Conradie
In this article we show that positive surjective isometries between symmetric spaces associated with semi-finite von Neumann algebras are projection disjointness preserving if they…

Extension of projection mappings
Pierre de Jager, Jurie Conradie
We show that a map between projection lattices of semi-finite von Neumann algebras can be extended to a Jordan -homomorphism between the von Neumann algebras if this map is defi…
