A survey of results on the d-c.e. and n-c.e. degrees
Get PDF© Springer International Publishing AG 2017.This paper is a survey on the upper semilattices of Turing and enumeration degrees of n-c.e. sets. Questions on the structural properties of these semilattices, and some model-theoretic properties are considered
