The Cut Elimination and the Nonlengthening Property for the Sequent Calculus with Equality
نویسندگان
چکیده
We show how Leibnitz.s indiscernibility principle and Gentzen's original work lead to extensions of the sequent calculus to first order logic with equality and investigate the cut elimination property. Furthermore we discuss and improve the nonlengthening property of Lifshitz and Orevkov.

An Isomorphism Between Cut-Elimination Procedure and Proof Reduction
This paper introduces a cut-elimination procedure of the intuitionistic sequent calculus and shows that it is isomorphic to the proof reduction of the intuitionistic natural deduction with general elimination and explicit substitution. It also proves strong normalization and Church-Rosser property of the cut-elimination procedure by projecting the sequent calculus to the natural deduction with ...
متن کاملNon-commutativity and MELL in the Calculus of Structures
We introduce the calculus of structures: it is more general than the sequent calculus and it allows for cut elimination and the subformula property. We show a simple extension of multiplicative linear logic, by a self-dual noncommutative operator inspired by CCS, that seems not to be expressible in the sequent calculus. Then we show that multiplicative exponential linear logic benefits from its...
متن کاملMELL in the calculus of structures
Gentzen’s sequent calculus is a tool to study properties of logics independently of semantics. The main property is cut-elimination which entails the subformula property and consistency. It is also the basis of methods of automated deduction. Although the sequent calculus is very appropriate for classical logic, it raises some concerns in dealing with more refined logics like linear logic. An e...
متن کاملCut elimination in coalgebraic logics
We give two generic proofs for cut elimination in propositional modal logics, interpreted over coalgebras. We first investigate semantic coherence conditions between the axiomatisation of a particular logic and its coalgebraic semantics that guarantee that the cut-rule is admissible in the ensuing sequent calculus. We then independently isolate a purely syntactic property of the set of modal ru...
متن کاملComplexity Analysis of Cut Elimination in First Order Based Logics
The worst-case complexity of cut elimination in sequent calculi for first order based logics is investigated in terms of the increase in logical depth of the deduction. It is shown that given a calculus satisfying a general collection of sufficient conditions for cut elimination and given a deduction with cuts, there exists a cut free deduction with a logical depth, in the worst case, hyper-exp...
