Distributed Knowing How

Distributed knowledge is a key concept in the standard epistemic logic of knowledge-that.In this paper, we propose a corresponding notion of distributed knowledge-how and study its logic.Our framework generalizes two existing traditions in the logic of know-how: the individual-based multistep framework and the coalition-based single-step framework.In particular, we assume a group can accomplish more than what its individuals can jointly do.The distributed knowledge-how is based on the distributed knowledge-that of a group whose multi-step strategies derive from distributed actions that subgroups can collectively perform.As the main result, we obtain a sound and strongly complete proof system for our logic of distributed knowledge-how, which closely resembles the logic of distributed knowledge-that in both the axioms and the proof method of completeness.
