Formal language theorem From Wikipedia, the free encyclopedia

Remove ads

In formal language theory, the Büchi–Elgot–Trakhtenbrot theorem states that a language is regular if and only if it can be defined in monadic second-order logic (MSO): for every MSO formula, we can find a finite-state automaton defining the same language, and for every finite-state automaton, we can find an MSO formula defining the same language. The theorem is due to Julius Richard Büchi,[1] Calvin Elgot,[2] and Boris Trakhtenbrot.[3][4]
