the main purpose of this article is to study common-third triad pairs in the chamber music of alfred schnittke. this harmonic device consists of major and minor triads which are a semitone apart and have the same chordal third; c major and c# minor, which will be labeled c.t. e (common-third e), d major and eb minor labeled as c.t. f#, etc. after a short introduction on the history of shared el...

*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...

In the companion paper (Towards a “sophisticated” model of belief dynamics. Part I), a general framework for realistic modelling of instantaneous states of belief and of the operations involving them was presented and motivated. In this paper, the framework is applied to the case of belief revision. A model of belief revision shall be obtained which, firstly, recovers the Gärdenfors postulates ...

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...
