Abstract

We construct computably enumerable degrees a < b such that all computably enumerable degrees c with a < c < b isolate some d. c. e. degree d.

We show that the theory of the partial ordering of the computably enumerable degrees in any given nontrivial interval is undecidable and has uncountably many 1-types.

We investigate the orbit of a low computably enumerable (c.e.) set under automorphisms of the partial order E of c.e. sets under inclusion. Given an arbitrary low c.e. set A and an arbitrary noncomputable c.e. set C, we use the New Extension Theorem of Soare to construct an automorphism of E mapping
