We study the cone avoidance and the upper cone avoidance of two substructures of $m$-introimmune Turing degrees. We show that the substructure of the $m$-introimmune Turing degrees satisfies the cone avoidance property, and that the substructure of the computably enumerable $m$-introimmune Turing degrees satisfies the upper cone avoidance property.

Abstract

We study the cone avoidance and the upper cone avoidance of two substructures of $m$-introimmune Turing degrees. We show that the substructure of the $m$-introimmune Turing degrees satisfies the cone avoidance property, and that the substructure of the computably enumerable $m$-introimmune Turing degrees satisfies the upper cone avoidance property.
