In modal logic, when adding a syntactic property to an axiomatisation, this property will semantically become true in all models, in all situations, under all circumstances. For i...

The research aim of this paper is to represent everydaylife patterns of thought like "Because I know, what you think I think ..." by a process on a machine, which is inv...
We implement a specific protocol for bit exchange among card-playing agents in three different state-of-the-art epistemic model checkers and compare the results. Key words: Crypto...

We present an epistemic logic incorporating dynamic operators to describe information changing events. Such events include epistemic changes, where agents become more informed abo...
In the clock semantics for epistemic logic, two situations are indistinguishable for an agent when it makes the same observation and the time in the situations is the same. The pa...
We propose a purely logical framework for planning in partially observable environments. Knowledge states are expressed in a suitable fragment of the epistemic logic S5. We show h...
Epistemic logic allows to reason not only about situations, but also about the knowledge that a set of agents have about situations. In later years, epistemic logic has been appli...
The proof theory of multi-agent epistemic logic extended with operators for distributed knowledge is studied. Distributed knowledge of A within a group G means that A follows from ...
Arbitrary public announcement logic (APAL) is an extension of multi-agent epistemic logic that allows agents' knowledge states to be updated by the public announcement of (pos...
Some natural epistemic properties which may arise in applications can only be expressed in standard epistemic logic by formulae which are exponentially long in the number of agent...
