SUMMARY:Computability Learning Seminar
CLASS:PUBLIC
DESCRIPTION:MICHAEL DEVEAU\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY OF
  WATERLOO\n\n\"Generalizing $\\omega^k$-c.e. for Relativization - Part 2\"
 \n\nWe finish the proof of a characterization of $A \\leq_{bT} B^b$ that w
 e\nstarted last time. We then use this to motivate a more general\ncharact
 erization\, namely when $A \\leq{bT} B^{nb}$. Finally\, we begin\nthe proo
 f of a weak non-collapse theorem which uses this expanded\ncharacterizatio
 n.\n\nMC 5413
