确定树语言的Wadge层次结构
The Wadge Hierarchy of Deterministic Tree Languages
摘要:
我们提供了一个完整的描述的Wadge层次结构的确定性可识别集的无限树。特别是,我们给出了一个基本的过程,以确定是否一个确定性树语言是连续约简到另一个。这扩展了瓦格纳的结果的层次结构的欧米茄-正则语言的话的情况下,树。
英文摘要:
We provide a complete description of the Wadge hierarchy for deterministically recognisable sets of infinite trees. In particular we give an elementary procedure to decide if one deterministic tree language is continuously reducible to another. This extends Wagner's results on the hierarchy of omega-regular languages of words to the case of trees.
