dc.description.abstract | It is proved that if 1 < m < 2p ≤ n for some integer p then the elementary theories of posets of m-c.e. n-c.e. e-degrees are distinct. It is proved also that the structures 〈D2n ≤ P〉 and 〈D2n ≤ P〉 are not elementary equivalent where P is the predicate P(a) = "a is a π1 0 e-degree". | |
