Title
Admissibility of Structural Rules for Contraction-Free Systems of Intuitionistic Logic
Abstract
We give a direct proof of admissibility of cut and contraction for the contraction-free sequent calculus G4ip for intuitionistic propositional logic and for a corresponding multi-succedent calculus: this proof extends easily in the presence of quantifiers, in contrast to other. indirect, proofs. i.e.. those which use induction on sequent weight or appeal to admissibility of rules in other calculi.
