We propose some variants of a multi-modal of joint action, preference and knowledge that support reasoning about epistemic games in strategic form. The first part of the paper deals with games with complete information. We first provide syntactic proofs of some well-known theorems in the area of...

Heifetz, Meier and Schipper (2005) introduced a generalized state-space model that allows for non-trivial unawareness among several individuals and strong properties of knowledge. We show that this generalized state-space model arises naturally if states consist of maximally consistent sets of...

Building on the analysis of Bonanno (2025) we introduce a simple modal logic containing three modal operators: a unimodal belief operator B, a bimodal conditional operator and the unimodal global operator □. For each AGM axiom for belief revision, we provide a corresponding modal axiom. The...
