ABSTRACT. The theory of measures in a topological space, as developed by V. S. Varadarajan for the algebra C of bounded continuous functions on a completely regular topological space, is extended to the context of an arbitrary uniformly closed algebra A of bounded real-valued functions. Necessary and sufficient conditions are given for A * to be represented in the natural way by a space of regular finitely-additive set functions. The concepts of additivity and tightness for these set functions are considered and some remarks about weak convergence are made.
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.
