Low Level Nondelegability Results: Domination and Recursive Enumeration

Mingzhong Cai, Richard A. Shore
2013 Journal of Symbolic Logic (JSL)  
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] .)  ...

Simple stable homogeneous groups

Alexander Berenstein
2003 Journal of Symbolic Logic (JSL)  
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  ...

Anti-Complex Sets and Reducibilities with Tiny Use

Johanna N. Y. Franklin, Noam Greenberg, Frank Stephan, Guohua Wu
2013 Journal of Symbolic Logic (JSL)  
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  ...  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  ...

Generic muchnik reducibility and presentations of fields

Rod Downey, Noam Greenberg, Joseph S. Miller
2016 Israel Journal of Mathematics  
We finish by considering generic Muchnik reducibility of a countable structure A to an arbitrary structure B.  ...  This allows us to answer a question of Knight, Montalbán, and Schweber.  ...  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.  ...

On low for speed oracles [article]

Laurent Bienvenu, Rod Downey
2017 arXiv   pre-print
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  ...  Bienvenu acknowledges support of ANR-15-CE40-0016-01 RaCAF grant, Downey thanks the Marsden Fund of New Zealand, and the LIRMM (University of Montpellier) where this research was undertaken.  ...

On the Computational Content of the Theory of Borel Equivalence Relations

Nikolay Bazhenov, Benoit Monin, Luca San Mauro, Rafael Zamora
2021
The presented results correspond to three main research focuses: (i) the poset of degrees of equivalence relations on reals under computable reducibility; (ii) the complexity of the equivalence relations  ...  To see this, we rely on Jockusch's result [19] that each Turing degree which is not hyperimmune-free contains infinitely many tt-degrees. Let d be a minimal Turing degree below 0 1 .  ...  In ERp2 ω q, there are 2 ℵ 0 degrees which form pairwise a minimal pair. Proof. Let X, Y be reals such that X ę T Y 1 . We claim that EptXuq and EptY uq is a minimal pair.  ...
