Computably enumerable set - Wikipedia

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). WebI read that recursively enumerable languages are closed under intersection but not under set difference. We know that, A ∩ B = A − ( A − B).
