The authors investigate "partial meet contraction functions", which are defined to yield the intersection of some nonempty family of maximal subsets of the theory that fail to imply the proposition being eliminated, and basic properties of these functions are established.
Conceptual spaces - the geometry of thought
- P. Gärdenfors
- Psychology
- 2000
Peter Gardenfors's theory of conceptual spaces presents a framework for representing information on the conceptual level and shows how conceptual spaces can serve as an explanatory framework for a number of empirical theories, in particular those concerning concept formation, induction, and semantics.
Revisions of Knowledge Systems Using Epistemic Entrenchment

- 7 March 1988
A representation theorem is proved which says that a revision method for a knowledge system satisfies the set of rationality postulates, if and only if, there exists an ordering of epistemic entrenchment satisfying the appropriate constraints such that this ordering determines the retraction priority of the facts of the knowledge system.

The stable marriage problem, i.e., the problem of assigning the members of two disjoint sets to one another is extended to the case in which individual preferences are represented by weak orderings…
Knowledge in Flux: Modeling the Dynamics of Epistemic States

- 2 June 2008
Knowledge in Flux presents a theory of rational changes of belief, focusing particularly on revisions that occur when the agent receives new information that is inconsistent with the present…
