{wiki=Büchi-Elgot-Trakhtenbrot_theorem}
The Büchi-Elgot-Trakhtenbrot theorem is a result in the field of formal languages and automata theory, specifically concerning the expressiveness of certain types of logical systems and their relationship to automata. The theorem establishes a correspondence between regular languages and certain logical formulas, which is a significant topic in the study of the foundations of computer science, particularly in the areas of model checking and verification.
