Beyond Borel-amenability: scales and superamenable reducibilities

Logic 2010-03-25 v1

Abstract

We analyze the degree-structure induced by large reducibilities under the Axiom of Determinacy. This generalizes the analysis of Borel reducibilities given in references [1], [6] and [5] e.g. to the projective levels.
