广义弦拓扑与导出Koszul对偶

Generalized String Topology and Derived Koszul Duality

Aaron M Royer

摘要:

Gruher和Salvatore的广义弦拓扑构造给闭定向流形$M$上的任何$E_n$ -代数$A$的丛分配了全空间同调上的交型运算的集合。这些操作是在Thom同构下通过Thom谱$A^{-TM}$上的$H_n$ -环结构实现的.我们刚性化和扩展这一建设的一个函子连接同伦理论的空间和谱参数化的$M$的同伦理论的模谱的Atiyah-Milnor-Spanier-Whitehead双$M^{-TM} \simeq \bbD M$。然后,使用$\infty$ -范畴版本的森田理论,我们给出了另一种描述我们的建设在派生的Koszul对偶(别名棒-cobar对偶)之间的$Σ^\infty_+ ΩM$和$\bbD M$。

英文摘要:

The generalized string topology construction of Gruher and Salvatore assigns to any bundle of $E_n$-algebras $A$ over a closed oriented manifold $M$ a collection of intersection-type operations on the homology of the total space. These operations are realized by an $H_n$-ring structure on the Thom spectrum $A^{-TM}$ under the Thom isomorphism. We rigidify and extend this construction to a functor connecting the homotopy theory of spaces and spectra parametrized by $M$ to the homotopy theory of module spectra over the Atiyah-Milnor-Spanier-Whitehead dual $M^{-TM} \simeq \bbD M$. Then, using an $\infty$-categorical version of Morita theory, we give an alternative description of our construction in terms of the derived Koszul duality (alias bar-cobar duality) between $Σ^\infty_+ ΩM$ and $\bbD M$.
