Abstract

A recognizable infinite array language or recognizable ωω-language is defined as the image of a local ωω-language by an alphabetic morphism. Here, we introduce Wang systems for ωω-languages and prove that the class of ωω-languages obtained by Wang systems is the same as the class of recognizable ωω-languages. We give automata characterization to the recognizable ωω-languages. We provide an algorithm for learning recognizable infinite array languages from positive data and restricted superset queries.
