|Title:||Degree-invariant functions and uniform Borel reductions|
|Speaker:||Jan Reimann, Pennsylvania State University|
|A. Kechris asked whether Turing equivalence is a universal countable Borel equivalence relation. If this is true, it would imply that Martin's Conjecture on degree-invariant functions is false. We show that Turing equivalence cannot be universal by means of uniform reductions. This is joint work with A. Montalban and T. Slaman.|
