dc.description.abstract | A real x is δ1 1-Kurtz random (Π1 1-Kurtz random) if it is in no closed null δ1 1 set (Π1 1 set). We show that there is a cone of Π1 1-Kurtz random hyperdegrees. We characterize lowness for δ1 1-Kurtz randomness as being δ1 1-dominated and δ1 1-semi-traceable. © 2010 Elsevier B.V. | |
