Low Level Nondelegability Results: Domination and Recursive Enumeration
2013
Journal of Symbolic Logic (JSL)
Preserved Fulltext
We prove a variety of results, including, for example, that being array nonrecursive is not definable by a Σ1 or Π1 formula in the language (≤, REA) where REA stands for the "r.e. in and above" predicate ...
We study low level nondefinability in the Turing degrees. ...
(We can …nd such a pair by, for example, the construction of a minimal degree which is 2 but not 2 from [S2] .) ...

We generalize tools and results from first order stable theories to groups inside a simple stable strongly homogeneous model. ...
For example, a Turing degree which is both minimal and hyperimmune-free does not contain such sets because if deg T (X) is hyperimmune-free and minimal, then deg wtt (X) is also minimal, as every nonrecursive ...
The following are equivalent for a weak truth-table degree a containing an r.e. set. (1) For no very strong arrayF does a contains anF -ANR set. (2) For some very strong arrayF , a contains noF -ANR set ...

We show that, as for complexity, the natural arena for examining anti-complexity is the weak-truth table degrees. ...
A set A is anti-complex if and only if it is reducible to another set B with tiny use, whereby we mean that the use function for reducing A to B can be made to grow arbitrarily slowly, as gauged by unbounded ...

To see this, let I be an ideal of hyperimmune-free degrees (containing some noncomputable element), and let f be a ∆ 0 2 function dominating all computable functions. However: Proof. ...

Relativizing computations of Turing machines to an oracle is a central concept in the theory of computation, both in complexity theory and in computability theory(!). ...
An oracle A is low for speed if relativizing to A has essentially no effect on computational complexity, meaning that if a decidable language can be decided in time f(n) with access to oracle A, then it ...
