Abstract

This paper studies the locally testable languages (or ''events'') introduced by McNaughton and Papert. We characterize these languages by means of their syntactic semigroups and obtain wreath product and direct product decompositions for these semigroups. As a by-product of our study, we find an algebraic characterization of A. Ginzburg's generalized definite languages.
