Intrinsic Reducibilities
Authors:Timothy H. McNicholl
Abstract:Let . We show that for many reducibilities, the requirement that a relation be intrinsically reducible to the α‐th jump of a countable mode A has a syntactic equivalent. Furthermore, we show that many reducibilities coincide in such a situation.
Keywords:Intrinsically reducible  n‐query reducibility  Truth‐table reducibility  n‐recursive enumerability  Bounded query classes
