【 摘 要 】

The aim of this paper is to characterize those linear maps from avon~Neumann factor $A$ into itself which preserve the extreme pointsof the unit ball of $A$. For example, we show that if $A$ is infinite,then every such linear preserver can be written as a fixed unitaryoperator times either a unital $ast$-homomorphism or a unital$ast$-antihomomorphism.
