论文摘要
在本文中，已经确定了算术组的Eisenstein $ g_2（\ mathbb {z}）$的EISENSTEIN共同体，其系数在任何有限的尺寸最高重量不可减得的表示中都得到了确定。我们通过研究Borel-Serre紧凑型边界的共同体来实现这一目标。
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.
