Intuitionistic modal logics: epistemic reasoning with distributed knowledge

Abstract: In this article, we add a diamond to the parametrized box-based propositional language of intuitionistic doxastic logic and intuitionistic epistemic logic introduced by Artemov and Protopopescu. The main results of this article are the proofs of completeness with respect to their appropriate relational semantics of the resulting intuitionistic doxastic logic and intuitionistic epistemic logic with distributed knowledge.
