Abstract
The height of the Wadge Hierarchy for the Alternation Free Fragment of μ-calculus is known to be at least ε 0. It was conjectured that the height is exactly ε 0. We make a first step towards the proof of this conjecture by showing that there is no definable set in between the levels ω ω and ω 1 of the Wadge Hierarchy of Borel Sets. © 2008 Springer-Verlag Berlin Heidelberg.
