Logic of Questions and Public Announcements

Abstract

This paper aims to explore the role of questions in communication in a group of cooperative rational agents. Using epistemic representation of questions we employ the framework of public announcement logic to explore the information in the process of asking and replying questions in a group.

We show that some of the erotetic notions we introduce nicely correspond to the standard epistemic ones.
