Speaker: Liu Yong

Title: maximal d.r.e. degrees and avoiding the upper cone.

URL: http://www.comp.nus.edu.sg/~fstephan/logicseminar.html

Abstract: We will review briefly the strategy for avoiding the upper
cone of a given nonrecursive r.e. set, and the strategy for building a
maximal d.r.e. set. And explain how to combine these two strategies.
Therefore we can build a maximal d.r.e. set avoiding the upper cone of
a given nonrecursive r.e. set.
