$G_2(\mathbb{Z})$的边界和Eisenstein上同调

Boundary and Eisenstein Cohomology of $G_2(\mathbb{Z})$

Jitendra Bajpai, Lifan Guan

摘要:

本文确定了系数在任意有限维最高权不可约表示中的算术群$G_2(\mathbb{Z})$的Eisenstein上同调.我们通过研究Borel-Serre紧化边界的上同调来实现这一点。

英文摘要:

In this article, Eisenstein cohomology of the arithmetic group $G_2(\mathbb{Z})$ with coefficients in any finite dimensional highest weight irreducible representation has been determined. We accomplish this by studying the cohomology of the boundary of the Borel-Serre compactification.
