定向形式群的模叠加与周期复边性

Moduli stack of oriented formal groups and periodic complex bordism

Rok Gregoric

摘要:

介绍并研究了非连通谱栈$\mathcal M_\mathrm{FG}^\mathrm{or}$,即有向形式群的模栈。我们实现了色同伦理论的一些结果在这个堆栈的几何。例如,我们表明,它的下降谱序列恢复亚当斯-诺维科夫谱序列。对于周期复边$\mathrm{MP}$的两种$\mathbb E_\infty$ -形式,Thom谱和Snaith构造模型,我们描述了覆盖$\mathrm{Spec}(\mathrm{MP})\to\mathcal M_\mathrm{FG}^\mathrm{or}$的泛性质.我们证明了Quillen的著名定理复边界等价于断言$\mathcal M_\mathrm{FG}^\mathrm{or}$的底层普通栈是普通形式群$\mathcal M^\heartsuit_\mathrm{FG}$的经典栈。为了实现上述所有的,我们开发了一个函子的点的方法,非连接谱代数几何的基础。

英文摘要:

We introduce and study the non-connective spectral stack $\mathcal M_\mathrm{FG}^\mathrm{or}$, the moduli stack of oriented formal groups. We realize some results of chromatic homotopy theory in terms of the geometry of this stack. For instance, we show that its descent spectral sequence recovers the Adams-Novikov spectral sequence. For two $\mathbb E_\infty$-forms of periodic complex bordism $\mathrm{MP}$, the Thom spectrum and Snaith construction model, we describe the universal property of the cover $\mathrm{Spec}(\mathrm{MP})\to\mathcal M_\mathrm{FG}^\mathrm{or}$. We show that Quillen's celebrated theorem on complex bordism is equivalent to the assertion that the underlying ordinary stack of $\mathcal M_\mathrm{FG}^\mathrm{or}$ is the classical stack of ordinary formal groups $\mathcal M^\heartsuit_\mathrm{FG}$. In order to carry out all of the above, we develop foundations of a functor of points approach to non-connective spectral algebraic geometry.
