Standard and nonstandard representability of positive uncertainty orderings [PDF]
Kybernetika, 2014 Summary: Axioms are given for positive comparative probabilities and plausibilities defined either on Boolean algebras or on arbitrary sets of events. These axioms allow to characterize binary relations representable by either standard or nonstandard measures (i.e., taking values either on the real field or on a hyperreal field).
