A weakly-2-generic which bounds a minimal degree

چکیده
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 proof is rather novel since it is a computable full approximation construction where both the generic and the minimal degrees are ∆3 −∆2.

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...

متن کاملOn the Number of Minimal Surfaces with a given Boundary
In [TT78], Tomi and Tromba used degree theory to solve a longstanding problem about the existence of minimal surfaces with a prescribed boundary: they proved that every smooth, embedded curve on the boundary of a convex subset of R must bound an embedded minimal disk. Indeed, they proved that a generic such curve must bound an odd number of minimal embedded disks. White [Whi89] generalized thei...
متن کاملTwo Classes of Hyperbolic Surfaces in P Bernard Shiffman and Mikhail Zaidenberg
We construct two classes of singular Kobayashi hyperbolic surfaces in P. The first consists of generic projections of the cartesian square V = C×C of a generic genus g ≥ 2 curve C smoothly embedded in P. These surfaces have C-hyperbolic normalizations; we give some lower bounds for their degrees and provide an example of degree 32. The second class of examples of hyperbolic surfaces in P is pro...
متن کاملOn minimal degree simultaneous pole assignment problems
In this paper, we show that a generic r-tuple of m-input p-output linear systems is simultaneously pole assignable if r < m+ p and the McMillan degrees of the systems are not too different. We also obtain upper bounds for the degrees of the compensators which simultaneously assign the characteristic polynomials of the r-tuple of closed loop systems. The upper bounds are obtained for each of the...
