Algebra, proof theory and applications for an intuitionistic logic of propositions, actions and adjoint modal operators

We develop a cut-free nested sequent calculus as basis for a proof search procedure for an intuitionistic modal logic of actions and propositions. The actions act on propositions via a dynamic modality (the weakest precondition of program logics), whose left adjoint we refer to as “update” (the stro...
