The Wadge-Wagner hierarchy of omega-rational sets

Abstract : We present a unified treatment of the hierarchy defined, by Klaus Wagner for omega-rational sets and also introduced in the more general framework of descriptive set theory by William W. Wadge. We show that this hierarchy can be defined by syntactic invariants, using the concept of an omega-semigroup.
