A BRIEF SURVEY OF FRAMES FOR THE LAMBEK CALCULUS
Kosta Došen · Mathematical logic quarterly · 1992
Abstract Models 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. The purpose of this brief survey is to locate some open completeness problems for variants of the Lambek calculus in the context of completeness results based on various types of ternary relational models.
