ABSTRACT Intelligent Environments and other Computer Science sub-fields based on the
concepts of context and context-awareness are created with the explicit or implicit intention …

A continuous multi-utility fully represents a not necessarily total preorder on a topological
space by means of a family of continuous increasing functions. While it is very attractive for …

We characterize the possibility of determining all the maximal elements for a preorder on a
topological space by maximizing all the functions in a suitable family of upper …

In this paper we study the aggregation of fuzzy preferences on non-necessarily finite
societies. We characterize in terms of possibility and impossibility a family of models of …

The thesis presents some classical results concerning the Utility Theory. We present the
requirements that a preorder must satisfy in order to be representable with a utility function …
