Extending the Lambek Calculus with Classical Negation

Studia Logica, 2021
Let \textbf{NL} be the non-associative Lambek calculus and S (our symbol) be the ternary relational semantics for \textbf{NL} as defined in [\textit{K. Došen}, Z. Math. Logik Grundlagen Math. 38, No. 2, 179--187 (1992; Zbl 0793.03025)]. Moreover, let negation be classically interpreted when ``a world satisfies the negation of a formula if and only if ...

Classical Non-Associative Lambek Calculus

open access: yesStudia Logica, 2002
We introduce non-associative linear logic, which may be seen as the classical version of the non-associative Lambek calculus. We define its sequent calculus, its theory of proof nets, for which we give a correctness criterion and a sequentialization theorem, and we show proof search in it is polynomial.

A BRIEF SURVEY OF FRAMES FOR THE LAMBEK CALCULUS

Zeitschrift Für Mathematische Logik Und Grundlagen Der Mathematik, 1992
AbstractModels for the Lambek calculus of syntactic categories surveyed here are based on frames that are in principle of the same type as Kripke frames for intuitionistic logic. These models are extracted from the literature on models for relevant logics, in particular the ternary relationed models introduced in the early seventies.

Lambek Calculus Proofs and Tree Automata

open access: yes, 2001
We investigate natural deduction proofs of the Lambek calculus from the point of view of tree automata. The main result is that the set of proofs of the Lambek calculus cannot be accepted by a finite tree automaton. The proof is extended to cover the proofs used by grammars based on the Lambek calculus, which typically use only a subset of the set of ...

Lambek Calculus and its relational semantics: Completeness and incompleteness

open access: yesJournal of Logic, Language and Information, 1994
The problem of whether Lambek Calculus is complete with respect to (w.r.t.) relational semantics, has been raised several times, cf. van Benthem (1989a) and van Benthem (1991). In this paper, we show that the answer is in the affirmative. More precisely,

On the Selective Lambek Calculus

2005
An intermediate logical system in comparison with the non-associative (NL) and the associative Lambek Calculus(L) is obtained by extending their language by means of a so-called “combining permission”, which is used to regulate the introduction of a product formula in the scope of a derivation and to impose a control on applications of the association ...

Proof Nets for Lambek Calculus

Journal of Logic and Computation, 1992
The representation of a proof as you find it in textbooks is just a linear sequence of derivation steps. This does not mean that linear sequences of derivation steps are a good representation for computer generated and computer manipulated proofs. And in fact, for various calculi there are alternative and more compact representations of proofs, for ...
