On Proof Normalization in Linear Logic
نویسندگان
چکیده
We present a proof-theoretic foundation for automated deduction in linear logic. At rst, we systematically study the permutability properties of the inference rules in this logical framework and exploit these to introduce an appropriate notion of forward and backward movement of an inference in a proof. Then we discuss the naturally-arising question of the redundancy reduction and investigate the possibilities of proof normalization which depend on the proof search strategy and the fragment we consider. Thus, we can deene the concept of normal proof that might be the basis of works about automatic proof construction and design of logic programming languages based on linear logic.

Abstract Interpretation of Linear Logic Programming
Linear Logic is gaining momentum in computer science because it ooers a uniied framework and a common vocabulary for studying and analyzing diierent aspects of programming and computation. We focus here on models where computation is identiied with proof search in the sequent system of Linear Logic. A proof normalization procedure, called \focusing", has been proposed to make the problem of pro...
متن کاملNondeterministic Linear Logic
In this paper, we introduce Linear Logic with a nondeterministic facility, which has a self-dual additive connective. In the system the proof net technology is available in a natural way. The important point is that nondeterminism in the system is expressed by the process of normalization, not by proof search. Moreover we can incorporate the system into Light Linear Logic and Elementary Linear ...

متن کاملLinear Logic and Strong Normalization
Strong normalization for linear logic requires elaborated rewriting techniques. In this paper we give a new presentation of MELL proof nets, without any commutative cut-elimination rule. We show how this feature induces a compact and simple proof of strong normalization, via reducibility candidates. It is the first proof of strong normalization for MELL which does not rely on any form of conflu...
متن کاملStrong Normalization of Proof Nets Modulo Structural Congruences
This paper proposes a notion of reduction for the proof nets of Linear Logic modulo an equivalence relation on the contraction links, that essentially amounts to consider the contraction as an associative commutative binary operator that can float freely in and out of proof net boxes. The need for such a system comes, on one side, from the desire to make proof nets an even more parallel syntax ...
