In order to guarantee the existence of these utility functions sufficient properties are assumed in an axiomatic manner. In this paper we discuss these axioms, and a formal proof of the existence of linear utility functions. Furthermore, we consider the von-Neumann-Morgenstern Utility Theorem, its importance for game theory and economics, and a formalization thereof. The formalization includes precise definitions of the underlying concepts including continuity and independence of preferences. We make the dependencies more precise and highlight some consequences for a formalization of game theory.
