Bousfield-Segal空间

Bousfield-Segal spaces

Raffael Stenzel

摘要:

本文研究Bousfield-Segal空间,这是Julie Bergner根据Bousfield关于Eilenberg-Mac Lane对象的思想引入的一个概念。与Rezk的Segal空间类似,它们的定义方式使得Bousfield-Segal空间自然地配备了同伦相干分式运算来代替合成。在本文中,我们表明,伯格纳的模型结构的Bousfield-Segal空间实际上可以得到的模型结构的Segal空间作为一个本地化和一个余本地化。我们由此证明了Bousfield-Segal空间确实是Segal空间,并且它们精确地刻画了那些具有可逆箭头的空间。我们注意到完备的Bousfield-Segal空间恰好是同伦常数Segal空间,并推导出相应的模型结构给出了$\infty$ -群胚和同伦型理论的模型.

英文摘要:

This paper is a study of Bousfield-Segal spaces, a notion introduced by Julie Bergner drawing on ideas about Eilenberg-Mac Lane objects due to Bousfield. In analogy to Rezk's Segal spaces, they are defined in such a way that Bousfield-Segal spaces naturally come equipped with a homotopy-coherent fraction operation in place of a composition. In this paper we show that Bergner's model structure for Bousfield-Segal spaces in fact can be obtained from the model structure for Segal spaces both as a localization and a colocalization. We thereby prove that Bousfield-Segal spaces really are Segal spaces, and that they characterize exactly those with invertible arrows. We note that the complete Bousfield-Segal spaces are precisely the homotopically constant Segal spaces, and deduce that the associated model structure yields a model for both $\infty$-groupoids and Homotopy Type Theory.
