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\"\n\nJust 
 as the arithmetic hierarchy characterizes reductions below\nvarious Turing
  jumps of $\\emptyset$\, Anderson and Csima showed that\nthe Ershov hierar
 chy -- related to the notion of $\\omega^k$-c.e.\n-- characterizes reduct
 ions of bounded Turing jumps of $\\emptyset$.\nWe discuss how to relativiz
 e this to reductions below bounded Turing\njumps of an arbitrary set.\n\nM
