An operation of contraction for a set \(A\) of sentences is an operation such that for any sentence \(\alpha\), \(A - \alpha\), the outcome of contracting \(A\) by \(\alpha\), is a subset of \(A\) that does not imply \(\alpha\) (unless \(\alpha\) is logically true).

A Model for Structural Changes of Belief
Studia Logica, 2008The author presents a generalization of AGM partial meet contraction in which the language, as well as the current belief set, may be modified. In effect, it is a recipe for constructing such a variable-language contraction from a fixed-language one. Consider any belief set closed under classical consequence, formulated in a propositional language, and

The article aims at re-visiting the notion of rough truth proposed by Pawlak in 1987 [15] and investigating some of its ‘logical’ consequences. We focus on the formal deductive apparatus $\cal L_R$, that is sound and complete with respect to a semantics based on rough truth.

Belief Stickiness and Belief Change
2006A series of rule modifications or improvements to the non-market economy anti-dumping law is a second best choice for NMEs. These economies want their transitions to be recognized with full scale country reclassifications as “market economies.” A reclassification would be the ultimate formal rule change to the anti-dumping laws.

A Logic of Belief Stasis and Belief Change
2006This chapter lays out a coherent logic of both belief stasis and belief change. It specifies the conditions under which static beliefs could become more dynamic. It also presents testable hypotheses with respect to how U.S. and EU beliefs regarding NMEs have affected the implementation of trade remedy laws. Traditional neoclassical economic accounts of

Belief Revision in a Changing World
1994Several authors (Keller and Winslett 1985, Winslett 1988, Katsuno and Mendelzon 1989, Morreau and Rott 1991) have recently argued for a distinction in the way beliefs are updated with new information. They distinguish between information that tells the agent that the world has changed over time and information that fills in or corrects the agent's ...

Change of belief or change of meaning?
1973I should like to begin by noting that while I regard it as a considerable privilege that I should be addressing you at all this evening, it is to me a still greater one that I should be addressing you first rather than second. This is an order of speakers quite the reverse of what the printed program might have led you to suspect, and I want to comment

Belief Change on Rational Rankings
Proceedings of the TwentyFirst International Conference on Principles of Knowledge Representation and ReasoningWe introduce a new epistemic space: the space of rational rankings. This space is very useful for understanding some aspects of belief dynamics. In particular, the issues which concern improving the new information. Thus, we define in a very clear and succinct way a class of operators capturing the fact that the new information is improved.
