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, the course deals with propositional and first-order inference from both semantic and axiomatic viewpoints, with also some material on first-order theories including celebrated ...

Girard introduced phase semantics as a complete set-theoretic semantics of linear logic, and Okada modified phase-semantic completeness proofs to obtain normalform theorems. On the basis of these ...
