$G_\infty$-环谱与$\beta$-环的Moore谱

$G_\infty$-ring spectra and Moore spectra for $β$-rings

Michael Stahlhauer

AI总结:

本文提出$G_\infty$-环谱概念,分析Moore谱的$G_\infty$-环结构,揭示全局等变幂运算与$\beta$-环结构的联系,为$\beta$-环理论提供新视角。

摘要:

本文引入了$G_\infty$-环谱的概念。它们是具有结构化乘法的全局等变同伦类型,在其等变同伦群和上同调群上产生幂运算。我们通过分析Moore谱何时能被赋予$G_\infty$-环结构来说明这一结构。这种$G_\infty$-结构对应于底层环上的幂运算,由Burnside环索引。我们展示了这些全局等变幂运算与$\beta$-环结构之间的密切关系,从而为$\beta$-环理论提供了新视角。

英文摘要:

In this paper, we introduce the notion of $G_\infty$-ring spectra. These are globally equivariant homotopy types with a structured multiplication, giving rise to power operations on their equivariant homotopy and cohomology groups. We illustrate this structure by analysing when a Moore spectrum can be endowed with a $G_\infty$-ring structure. Such $G_\infty$-structures correspond to power operations on the underlying ring, indexed by the Burnside ring. We exhibit a close relation between these globally equivariant power operations and the structure of a $β$-ring, thus providing a new perspective on the theory of $β$-rings.
