Convexity in semi-metric spaces, decision theory and consumer theory

Abstract

Convexity is a concept usually developed in vector spaces. However since the seventies of the 20th century, convexity is also study in metric spaces in general. In this paper we develop a theory of convexity - including convex real functions - in semi-metric spaces and we suggest some possible applications in Economics and Decision Theory.info:eu-repo/semantics/publishedVersio
