Generalized coherence and connection property of imprecise conditional previsions.

In this paper we consider imprecise conditional prevision assessments on random quantities with finite set of possible values. We use a notion of generalized coherence which is based on the coherence principle of de Finetti. We consider the checking of g-coherence, by extending some previous results obtained for imprecise conditional probability assessments. Then, we study a connection property of interval-valued g-coherent prevision assessments, by extending a result given in a previous paper for precise assessments.
