A Brief Note About Rott Contraction
نویسندگان
چکیده
One of the ways to model contraction functions for belief sets is epistemic entrenchment. The first step was provided by Gärdenfors in [5], who defined epistemic entrenchment and a contraction function in terms of it and related the latter with the AGM contraction function. Later Hans Rott in [16] presented an entrenchment based contraction function that does not satisfy recovery. In this paper we provide an axiomatic characterization of Rott Contraction.1

Contraction and Informational Value
*Thanks are due to Hans Rott and Maurice Pagnucco who have commented on the July draft of this essay and who subsequently sent me a draft of their ideas on contraction. I have sought here to explain how I came to change my mind and favor mild contractions (or severe withdrawals as Rott and Pagnucco call such contractions) and to indicate some of the relations between the approach of Rott and Pa...
متن کاملIterated Belief Contraction from First Principles
Importance of contraction for belief change notwithstanding, literature on iterated belief change has by and large centered around the issue of iterated belief revision, ignoring the problem of iterated belief contraction. In this paper we examine iterated belief contraction in a principled way, starting with Qualified Insertion, a proposal by Hans Rott. We show that a judicious combination of ...
متن کاملRevision by comparison as a unifying framework: Severe withdrawal, irrevocable revision and irrefutable revision
Fermé and Rott (‘Revision by Comparison’, Artificial Intelligence 157, 2004) introduced a binary operation of ‘revision by comparison’ and pointed out that this method of changing epistemic states has both characteristics of belief contraction (with respect to the ‘reference sentence’) and characteristics of belief revision (with respect to the ‘input sentence’). Using revision by comparison as...
متن کاملGeneralized $F$-contractions in Partially Ordered Metric Spaces
We discuss about the generalized $F$-contraction mappings in partially ordered metric spaces. For this, we first introduce the notion of ordered weakly $F$-contraction mapping. We also present some fixed point results about this type of mapping in partially ordered metric spaces. Next, we introduce the notion of $acute{mathrm{C}}$iri$acute{mathrm{c}}$ type generalized ordered weakly $F$-contrac...
متن کاملContraction: On the Decision-Theoretical Origins of Minimal Change and Entrenchment
We present a decision-theoretically motivated notion of contraction which, we claim, encodes the principles of minimal change and entrenchment. Contraction is seen as an operation whose goal is to minimize loses of informational value. The operation is also compatible with the principle that in contracting A one should preserve the sentences better entrenched than A (when the belief set contain...
