Wadge hierarchy

http://dbpedia.org/resource/Wadge_hierarchy an entity of type: WikicatMathematicalLogicHierarchies

In descriptive set theory, within mathematics, Wadge degrees are levels of complexity for sets of reals. Sets are compared by continuous reductions. The Wadge hierarchy is the structure of Wadge degrees. These concepts are named after William W. Wadge. rdf:langString
