Inhalt der Lehrveranstaltung

Due to the Knowledge of Preconditions principle, which has universal validity, what has been in the domain of philosophy under the name of formal epistemology, has gained a second life in logic and computer science under the name of epistemic logic.

Epistemic logic started as a study of the laws of static knowledge. The proliferation of multi-agent and distributed systems called for a more dynamic view of knowledge and guaranteed the success of what is now called dynamic epistemic logic. It studies how knowledge changes as a result of communication between the agents. Dynamic epistemic logic has connections with database theory, game theory, and economics.

In the course, we first study standard epistemic modal logics for multi-agent systems and discuss concepts such as individual, group, distributed, and common knowledge. These concepts will be illustrated by some famous examples, such as Cheryl's Birthday, the Muddy Children Puzzle, the Two Generals' Problem, and the Alternating Bit Protocol. We study the syntax and semantics of epistemic logics. We then introduce the dynamic element, i.e., the means of expressing communication and the resulting change in knowledge of the agents. We first study simple updates corresponding to public announcements and discuss whether public
announcements must necessarily be successful, i.e., whether a public announcement of a particular fact brings about the knowledge of this fact by the agents. We then turn our attention to a more general model of communication called action models.

The course will mostly be based on the book "Hans van Ditmarsch, Wiebe van der Hoek, Barteld Kooi, 'Dynamic Epistemic Logic'. Springer, 2007 (Volume 337 of Synthese Library)"
