چکیده

We show that over the base system P− + Σ2-bounding, the existence of a 1-generic degree < 0′′ bounding a minimal degree is equivalent to Σ2-induction.

Genericity and Non-bounding in the Enumeration degrees

The structure of the semi lattice of enumeration degrees has been investigated from many aspects. One aspect is the bounding and nonbounding properties of generic degrees. Copestake proved that every 2-generic enumeration degree bounds a minimal pair and conjectured that there exists a 1-generic degree that does not bound a minimal pair. In this paper we verify this longstanding conjecture by c...

A weakly-2-generic which bounds a minimal degree

Jockusch showed that 2-generic degrees are downward dense below a 2-generic degree, but in the case of 1-generic degrees Kumabe, and independently Chong and Downey constructed a minimal degree computable from a 1-generic degree. We explore the tightness of these results. We solve a question of Barmpalias and Lewis-Pye by constructing a minimal degree computable from a weakly 2-generic one. The ...

Bounding and nonbounding minimal pairs in the enumeration degrees

We show that every nonzero ∆ 2 e-degree bounds a minimal pair. On the other hand, there exist Σ 2 e-degrees which bound no minimal pair.
