$E_{\infty}$环空间有什么用?

What are $E_{\infty}$ ring spaces good for?

J. P. May

摘要:

无限闭路空间理论,无论是加法还是乘法,主要源于两个基本动机。一个是解决几何拓扑中的计算问题。另一个是为了更好地理解代数K理论。亚当斯猜想是第一个动机所固有的,而奎伦对这个猜想的证明直接导致了他最初的、可计算的、代数K理论的定义。反过来,代数K理论的无限循环的理解反馈到几何拓扑的计算问题。例如,使用无限闭路空间理论导致一种方法,用于确定特征类的拓扑丛(在奇素数)在上同调的有限群。我们只解释了一点关于这一切是如何工作的,重点是E无穷环空间所扮演的核心角色。

英文摘要:

Infinite loop space theory, both additive and multiplicative, arose largely from two basic motivations. One was to solve calculational questions in geometric topology. The other was to better understand algebraic K-theory. The Adams conjecture is intrinsic to the first motivation, and Quillen's proof of that led directly to his original, calculationally accessible, definition of algebraic K-theory. In turn, the infinite loop understanding of algebraic K-theory feeds back into the calculational questions in geometric topology. For example, use of infinite loop space theory leads to a method for determining the characteristic classes for topological bundles (at odd primes) in terms of the cohomology of finite groups. We explain just a little about how all that works, focusing on the central role played by E infinity ring spaces.
