“…[16,17,22,38]). Indeed, in several of these situations there are theorems of automatic continuity: to put an example, any translation-invariant linear order defined on a group is continuous as regards the order topology, and a group endowed with a translationinvariant total (linear) order is actually a topological group with respect to the order topology (see [38] for further details).…”

Abstract. Let G be a topological locally compact group (abelian or not) endowed with a left Haar measure and a left translation-invariant and strongly continuous strict partial ordering -< . We consider a positive finite measure v on G, such that this order is v-separable. Then, we associate to each positive relatively invariant measure A on G a class of continuous numerical representations for the order -< . IntroductionIn Economics, the notion of utility function is a useful tool in the theory of consumption. Suppose that a society of consumers (constituted by individulas, households, tribes, etc, ...) is given and that the members of this society have an order of preferences for the products they want to choose. Then an utility function is a numerical representation of this order. It transforms preferences into numerical scales. Therefore, numerical representations of preordered sets are tools for decision making.In Mathematics, the problem of representability of complete ordering by means of a numerical function was posed long ago by Cantor (1895, 1897) (see [3] and [4]). Different studies and solutions of that problem can be found in the paper [20] of Milgram (1939) and the papers ([7, 8]) of Debreu (1954Debreu ( , 1959 or the paper of Fishburn (see [10]) in 1970.A natural extension of these ideas is the study of this problem for preorders or partial orders (not necessarily completes) in topological spaces. This study has producted a rich literature: see the works by Eilenberg (1941), Debreu (1954), Fleischer (1961 and Jaffray (1975) on completely preordered 1991 Mathematics Subject Classification: Primary 28C10, 54F05; Secondary 06F15, 90A10.
