  1. Properly [image] Enumeration Degrees and the High/Low Hierarchy.Matthew Giorgi, Andrea Sorbi & Yue Yang - 2006 - Journal of Symbolic Logic 71 (4):1125 - 1144.
    We show that there exist downwards properly $\Sigma _{2}^{0}$ (in fact noncuppable) e-degrees that are not high. We also show that every high e-degree bounds a noncuppable e-degree.
