Regular languages definable by Lindström quantifiers

Zoltán Ésik, Kim G. Larsen (2003)

RAIRO - Theoretical Informatics and Applications - Informatique Théorique et Applications

In our main result, we establish a formal connection between Lindström quantifiers with respect to regular languages and the double semidirect product of finite monoids with a distinguished set of generators. We use this correspondence to characterize the expressive power of Lindström quantifiers associated with a class of regular languages.
