环谱和Thom谱的单位

Units of ring spectra and Thom spectra

Matthew Ando, Andrew J. Blumberg, David J. Gepner, Michael J. Hopkins, Charles Rezk

摘要:

我们回顾和扩展了Thom谱理论和相关的取向障碍理论。我们记得(从May,Quinn和Ray),一个交换环谱A有一个单位为gl(A)的谱。对于光谱f的图:b-> bgl(A),我们联系了一个交换A-代数Thom谱Mf,它允许一个交换A-代数映射到R当且仅当b-> bgl(A)-> bgl(R)为零.若A是结合环谱,则对于空间f:B-> BGL(A)的映射,我们给出A-模Thom谱Mf,它允许R-定向当且仅当B-> BGL(A)-> BGL(R)为零。我们还注意到BGL(A)对A理论的曲折进行了分类。我们开发和比较两种方法的理论托姆光谱。第一个涉及A-无限和E-无限空间的刚性模型。我们的第二种方法是通过无限类别。为了将这些方法相互比较并与经典理论进行比较,我们从森田理论的角度刻画了Thom谱函子。

英文摘要:

We review and extend the theory of Thom spectra and the associated obstruction theory for orientations. We recall (from May, Quinn, and Ray) that a commutative ring spectrum A has a spectrum of units gl(A). To a map of spectra f: b -> bgl(A), we associate a commutative A-algebra Thom spectrum Mf, which admits a commutative A-algebra map to R if and only if b -> bgl(A) -> bgl(R) is null. If A is an associative ring spectrum, then to a map of spaces f: B -> BGL(A) we associate an A-module Thom spectrum Mf, which admits an R-orientation if and only if B -> BGL(A) -> BGL(R) is null. We also note that BGL(A) classifies the twists of A-theory. We develop and compare two approaches to the theory of Thom spectra. The first involves a rigidified model of A-infinity and E-infinity spaces. Our second approach is via infinity categories. In order to compare these approaches to one another and to the classical theory, we characterize the Thom spectrum functor from the perspective of Morita theory.
