A canonical model for interactive unawareness

Aviad Heifetz, Martin Meier, Burkhard C. Schipper

Research output: Contribution to conferencePaperpeer-review


Heifetz, Meier and Schipper (2006) 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 formulas in an appropriate logical formulation.
