纤维自等价分类空间的有理同伦型

Rational Homotopy Type of the Classifying Space for Fibrewise Self-Equivalences

Urtzi Buijs, Samuel B. Smith

摘要:

设p是具有有限基B和纤维F的单连通CW复形的纤维化。设aut_1(p)表示p的所有纤维同伦自等价空间的单位连通区,Baut_1(p)表示该拓扑幺半群的分类空间。给出了Baut_1(p)的微分分次李代数模型.利用这个模型,我们给出了由Baut_1(p)表示的有理同伦类型的分类结果,并得到了么半群aut_1(p)有理化后是双环空间的条件。

英文摘要:

Let p be a fibration of simply connected CW complexes with finite base B and fibre F. Let aut_1(p) denote the identity component of the space of all fibre-homotopy self-equivalences of p and Baut_1(p) the classifying space for this topological monoid. We give a differential graded Lie algebra model for Baut_1(p). We use this model to give classification results for the rational homotopy types represented by Baut_1(p) and also to obtain conditions under which the monoid aut_1(p) is a double loop-space after rationalization.
