In the present paper we study dominated operators acting on Banach-Kantorovich Lp-lattices, constructed by a measure m with values in the ring of all measurable functions. Using methods of measurable bundles of Banach-Kantorovich lattices, we prove the strong "zero-two" law for positive contractions of Banach-Kantorovich Lp-lattices.

Abstract. Following an idea of Ornstein and Sucheston, Foguel proved the so-called uniform "zero-two" law: let T :There are many papers devoted to generalizations of this law. In the present paper we provide a multi-parametric generalization of the uniform zero-two law for L 1 -contractions.
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.
