Extreme point methods in the study of isometries on certain non-commutative spaces
Pierre de Jager, Jurie Conradie
In this paper we characterize surjective isometries on certain classes of non-commutative spaces associated with semi-finite von Neumann algebras: the Lorentz spaces , as…

Multiplication operators on non-commutative spaces
Pierre de Jager, Louis Labuschagne
Boundedness and compactness properties of multiplication operators on quantum (non-commutative) function spaces are investigated. For endomorphic multiplication operators these pro…
