Thom谱的拓扑霍赫希尔德同调与自由闭路空间

Topological Hochschild homology of Thom spectra and the free loop space

A. J. Blumberg, R. L. Cohen, C. Schlichtkrull

摘要:

我们描述了环映射f:X->BF的Thom谱的环谱的拓扑霍赫希尔德同调,其中BF表示稳定球面纤维化的分类空间.为此,我们考虑BF上空间范畴的对称monoidal模型和相应的强对称monoidal Thom谱函子。我们的主要结果表明拓扑霍赫希尔德同调是自由闭路空间L(BX)上某个稳定丛的Thom谱.这导致了一大类环谱的拓扑霍赫希尔德同调的显式计算,包括所有经典的配边谱MO,MSO,MU等,Eilenberg-MacLane谱HZ/p和HZ。

英文摘要:

We describe the topological Hochschild homology of ring spectra that arise as Thom spectra for loop maps f: X->BF, where BF denotes the classifying space for stable spherical fibrations. To do this, we consider symmetric monoidal models of the category of spaces over BF and corresponding strong symmetric monoidal Thom spectrum functors. Our main result identifies the topological Hochschild homology as the Thom spectrum of a certain stable bundle over the free loop space L(BX). This leads to explicit calculations of the topological Hochschild homology for a large class of ring spectra, including all of the classical cobordism spectra MO, MSO, MU, etc., and the Eilenberg-Mac Lane spectra HZ/p and HZ.
