有理G-谱的代数模型

An introduction to algebraic models for rational G-spectra

David Barnes, Magdalena Kedziorek

摘要:

Greenlees等人的项目在理解有理G-谱的代数范畴方面取得了许多成功,分类了有限群的有理G-谱,SO(2),O(2),SO(3),自由和余自由G-谱以及任意紧李群的有理T-谱。本文分两部分对这一主题进行了介绍。第一章讨论了有理G-Mackey函子、Burnside环的作用和群函子的变换。它给出了有限G的有理Mackey函子的著名分类的完整证明。第二部分讨论了从等变稳定同伦理论得到有理G-谱代数模型所需要的方法和工具。总结了对称monoidal代数范畴的有理G-谱项分类的关键步骤。把这两个部分放在同一个地方,可以让我们清楚地看到代数分类和拓扑分类之间的相似性。

英文摘要:

The project of Greenlees et al. on understanding rational G-spectra in terms of algebraic categories has had many successes, classifying rational G-spectra for finite groups, SO(2), O(2), SO(3), free and cofree G-spectra as well as rational toral G-spectra for arbitrary compact Lie groups. This paper provides an introduction to the subject in two parts. The first discusses rational G-Mackey functors, the action of the Burnside ring and change of group functors. It gives a complete proof of the well-known classification of rational Mackey functors for finite G. The second part discusses the methods and tools from equivariant stable homotopy theory needed to obtain algebraic models for rational G-spectra. It gives a summary of the key steps in the classification of rational G-spectrain terms of a symmetric monoidal algebraic category. Having these two parts in the same place allows one to clearly see the analogy between the algebraic and topological classifications.
