Proof Nets for Lambek Calculus
University of Amsterdam, Fac. Math. & Comp. Sc. Plantage Muidergracht 24, 1018 TV Amsterdam, The Netherlands
The proof nets of linear logic are adapted to the non-commutative Lambek calculus. A different criterion for soundness of proof nets is given, which gives rise to new algorithms for proof search. The order sensitiveness of the Lambek calculus is reflected by the planarity condition on proof nets; this gives rise to a new non-provability check: balance.
