This paper models Aumann structures with complete lattices and discusses unawareness. In multi-attribute state space models, although previous studies discussing unawareness assume a family of spaces with a complete lattice, there is no model in which a standard state space is a complete...

This study focuses on discovered versions of coordination games with unawareness, and proposes a novel solution concept under unawareness named a successful-coordination equilibrium. In games with unawareness, coordination might fail because the models assume that agents are unaware of their...

This study discusses the convergence to a solution in simultaneous-move games with unawareness. Since games with unawareness assume players' unawareness of actions, in some plays, players might revise their subjective views when they observe opponents' play, which they were unaware of. Recently,...
