Linear maps on factors which preserve the extreme points of the unit ball
Vania Mascioni, Lajos Molnar
The aim of this paper is to characterize those linear maps from a von Neumann factor $\A$ into itself which preserve the extreme points of the unit ball of $\A$. For example, we sh…

Linear maps between C*-algebras whose adjoints preserve extreme points of the dual ball
Louis E. Labuschagne, Vania Mascioni
We give a structural characterisation of linear operators from one % -algebra into another whose adjoints map extreme points of the dual ball onto extreme points. We show t…

On Functions of Finite Baire Index
Fouad Chaatit, Vania Mascioni, Haskell P. Rosenthal
It is proved that every function of finite Baire index on a separable metric space is a -function, i.e., a difference of bounded semi-continuous functions on . In fact it…
