ON GROUPS WHICH ARE SYNTACTIC MONOIDS OF DETERMINISTIC CONTEXT-FREE LANGUAGES

Abstract

The author shows that the class of groups which are syntactic monoids of deterministic context-free languages is closed under restricted standard wreath products with virtually free top groups. This provides an answer to a question of T. Herbst.
