Beyond Borel-amenability: Scales and superamenable reducibilities

We analyze the degree-structure induced by large reducibilities under the Axiom of Determinacy. This generalizes the analysis of Borel reducibilities given in [1], [6] and [5] e.g. to the projective levels. Key words: Determinacy, Wadge hierarchy 2000 MSC: 03E15, 03E60
