WebTheorem 6 (Myhill-Nerode) Let Lbe a language over . If has in nitely many equivalence classes with respect to ˇ L, then Lis not regular. Otherwise, Lcan be decided by a DFA whose number of states is equal to the number of equivalence classes in with respect to ˇ L. Proof: If there are in nitely many equivalence classes, then it follows from ... WebTheorem 1 (Myhill-Nerode) A language L is regular if and only if there is a right congru-ence ∼ of finite index, that saturates L. From any finite automaton A = (Q,Σ,δ,s,F) …

WebTheorem 7.1. Let ⌃ be an alphabet and let A ⌃⇤ be a language over ⌃.ThenA is regular if and only if there are finitely many equivalence classes with respect to A.Moreover,ifA is regular, then the number of equivalence classes with respect to A is exactly the minimum number of states in a DFA for A.

A property P is nontrivial means there is a TM that satisfies it and there is a TM that does not satisfies it. A property P is trivial means either it is satisfied by all TMs or it is satisfied by no TMs. WebThe main theorem Theorem (Myhill-Nerode).
