Utility functions associated to relatively invariant measure on partially ordered locally compact groups

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 -< .
