关于$\mathrm{GL}(n,\mathbb{Z})$的扭曲上同调的Borel稳定域

On Borel's stable range of the twisted cohomology of $\mathrm{GL}(n,\mathbb{Z})$

Kazuo Habiro, Mai Katada

摘要:

Borel的稳定性和消灭定理给出了系数在代数$\mathrm{GL}(n,\mathbb{Z})$ -表示中的$\mathrm{GL}(n,\mathbb{Z})$的稳定上同调。我们计算改进的稳定范围,博雷尔评论。为了进一步提高Borel的稳定范围,我们将Kupers-Miller-Patzt方法应用于任何代数$\mathrm{GL}(n,\mathbb{Z})$ -表示.

英文摘要:

Borel's stability and vanishing theorem gives the stable cohomology of $\mathrm{GL}(n,\mathbb{Z})$ with coefficients in algebraic $\mathrm{GL}(n,\mathbb{Z})$-representations. We compute the improved stable range that Borel remarked about. In order to further improve Borel's stable range, we adapt the method of Kupers-Miller-Patzt to any algebraic $\mathrm{GL}(n,\mathbb{Z})$-representations.
