Resumo(s)
One 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.1
