  AGM's belief revision is one of the main paradigms in the study of belief
change operations. In this context, belief bases (prioritised bases) have been
largely used to specify the agent's belief state - whether representing the
agent's `explicit beliefs' or as a computational model for her belief state.
While the connection of iterated AGM-like operations and their encoding in
dynamic epistemic logics have been studied before, few works considered how
well-known postulates from iterated belief revision theory can be characterised
by means of belief bases and their counterpart in a dynamic epistemic logic.
This work investigates how priority graphs, a syntactic representation of
preference relations deeply connected to prioritised bases, can be used to
characterise belief change operators, focusing on well-known postulates of
Iterated Belief Change. We provide syntactic representations of belief change
operators in a dynamic context, as well as new negative results regarding the
possibility of representing an iterated belief revision operation using
transformations on priority graphs.
