Authors: Dominic Hughes Rob Van Glabbeek


A cornerstone of the theory of proof nets for unit-free multiplicative linear logic (MLL) is the abstract representation of cut-free proofs modulo inessential commutations of rules. The only known extension to additives, based on monomial weights, fails to preserve this key feature: a host of cut-free monomial proof nets can correspond to the same cut-free proof. Thus the problem of finding a satisfactory notion of proof net for unit-free multiplicative-additive linear logic (MALL) has remained open since the incep-tion of linear logic in 1986. We present a new definition of MALL proof net which remains faithful to the cornerstone of the MLL theory.
