WebJan 20, 2024 · A recursive language accepts every string of the language L and rejects every string over some alphabet that is not in the language. Let L is a language and imagine it … WebA recursively enumerable language is a computably enumerable subset of a formal language. The set of all provable sentences in an effectively presented axiomatic system is a computably enumerable set. Matiyasevich's theorem states that every computably enumerable set is a Diophantine set (the converse is trivially true).
