2-sequent calculus: classical modal logic

Abstract: "In this work we propose an extension of the Gentzen sequent calculus in order to deal with classical modal logics. We extend the notion of a sequent obtaining what we call a 2-sequent. For the obtained calculi we prove a cut elimination theorem. We compare our approach with the Hilbe...

Summary:Abstract: "In this work we propose an extension of the Gentzen sequent calculus in order to deal with classical modal logics. We extend the notion of a sequent obtaining what we call a 2-sequent. For the obtained calculi we prove a cut elimination theorem. We compare our approach with the Hilbert style approach."
