Ω幂与描述集合论
Omega-powers and descriptive set theory
摘要：
本文从描述集合论的观点出发，研究了有限字母表上字典可构的无限句子的集合。除此之外，这给出了一些真正的共解析集。字典是有限的情况下进行了研究，并给出了一个自然的例子，一组在水平欧米茄的Wadge层次结构。
英文摘要：
We study the sets of the infinite sentences constructible with a dictionary over a finite alphabet, from the viewpoint of descriptive set theory. Among other things, this gives some true co-analytic sets. The case where the dictionary is finite is studied and gives a natural example of a set at the level omega of the Wadge hierarchy.
