Dynamic Awareness

Abstract

We investigate how to model the beliefs of an agent who becomes more aware. We use the framework of Halpern and Rego (2013) by adding probability, and define a notion of a model transition that describes constraints on how, if an agent becomes aware of a new formula $\varphi$ in state $s$ of a model $M$, she transitions to state $s^{\ast }$ in a model $M^{\ast }$. We then discuss how such a model can be applied to information disclosure.
