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…

Isometries on non-commutative (quantum) Lorentz spaces associated with semi-finite von Neumann algebras
Pierre de Jager, Jurie Conradie
In this article we characterize the extreme points of the unit ball of a non-commutative (quantum) Lorentz space associated with a semi-finite von Neumann algebra. This enables us…
