Fermé, Eduardo L.Rodriguez, Ricardo O.2021-06-012021-06-011998http://hdl.handle.net/10400.13/3464One of the ways to model contraction functions for belief sets is epistemic entrenchment. The first step was provided by G¨ardenfors 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.1engAGMBelief contractionRecovery postulateRott contraction.Faculdade de Ciências Exatas e da Engenhariajournal article10.1093/jigpal/6.6.835
