Iterated Belief Contraction is a relatively less explored area in belief change and intuition for it is often driven by work in the area of iterated belief revision. For many of the iterable belief contraction functions defined in the literature, very little is known about their properties. In this paper we recall two iterable contraction functions, Natural contraction and Priority contraction, defined by Nayak and colleagues. Here we characterize both these contraction functions via some simple properties of iterated contraction.
