Research Type Theoretical We provide a representation theorem for the contraction which shows that it satisfies all the AGM postulates except for the controversial Recovery Postulate, and is a natural generalisation of entrenchment-based contraction. and Proof sketch: To prove satisfactions of the postulates, again the key is the ability to use disjunctions indirectly. For the other direction, (FC . ct) and (FC . 8) correspond to (EE1) (EE5) as in the AGM case. Also, in Theorem 7, it states: We show this using tableau.
