Abstract
The height of the Wadge Hierarchy for the Alternation Free Fragment of mu-calculus is known to be at least epsilon(0). It was conjectured that the height is exactly epsilon(0). We make a first step towards the proof of this conjecture by showing that there is no Delta(mu)(2) definable set in between the levels omega(omega) and omega(1) of the Wadge Hierarchy of Borel Sets.
