Journal of Logic and Computation, 18(5), 739-753.http://hdl.handle.net/10400.13/3452In this article, we propose an axiomatic characterization for ensconcement-based contraction functions, belief base functions proposed by Williams. We relate this function with other kinds of base contraction functions.engLogic of theory changeBelief basesBase contractionEnsconcement.Faculdade de Ciências Exatas e da Engenhariajournal article10.1093/logcom/exm093
