Abstract:First, Ornstein and Sucheston proved that for a given positive contrac-Such a result was labeled as "zero-two" law. In the present paper, we prove a generalized uniform "zero-two" law for multi-parametric family of positive contractions of the non-commutative L1-spaces. Moreover, we also establish a vector-valued analogous of the uniform "zero-two" law for positive contractions of L1(M, Φ)-the noncommutative L1-spaces associated with center valued trace.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
