In this paper we present a sequent calculus for propositional dynamic logic built using an enriched version of the tree-hypersequent method and including an infinitary rule for the iteration operator.

From classical logic, it deals with propositional and first-order inference from both semantic and axiomatic viewpoints, with also some material on first-order theories including celebrated theorems ...

We translate the classical propositional calculus (CPC) and the intuitionistic propositional calculus (IPC) into the assertive part of $\scr {L}^ {P}$ and show that this translation allows us to ...
