Vagueness and Intransitivity in Decision Theory
Abstract : The aim of this presentation is to provide an overview of the manifestation of vagueness in decision and preferences, as well as an introduction to the modelling of vagueness by means of semi-orders and the associated preference structures. Such models are used to represent preferences whose patterns are closely related to sorites series. We shall therefore discuss the relationship between semi-orders and the Sorites Paradox.
