.... An) A . Rational Monotony in Gentzen style is If j6 : A1 An) for all A1 ; An 2 , then j A implies [ j A . 3 if added, will cause the inference relation collapsing to a monotonic one, such as Monotonicity, Transitivity and Contraposition (see [Kraus et al. 90] Freund et al. 92] were proposed for special nonmonotonic inference relation, such as If j A; then [ j A or [ j :A (Determinacy Preservation) see [Makinson 93] If j A and , then j A (Antitonicity) see [Kaluzhny and Lehmann 95] The underlying intuition of those rules is a long story 2 , but ....

Nonmonotonic Reasoning: From finitary relations to infinitary .. - Freund, Lehmann (1994)   Self-citation (Freund Lehmann)   (Correct)

....operations that are not rational (not even on singletons) The following provides a handy characterization of rational operations. It is closely related to the di erent equivalent rules of restricted transitivity shown to be equivalent to Rational Monotonicity (in the nitary framework) in [7]. The following theorem provides a characterization of rational operations. Theorem 21 An operation C is rational i it is supraclassical, left absorbing and satis es C(X) Cn(X; C(Y ) for any X;Y L such that Y C(X) and X is consistent with C(Y ) Proof : For the only if part, suppose C ....
