论文摘要
本文涉及整体通用线性组的表示。任何一对挂钩Weyl模块之间的扩展组$ ext^2 $是通过详细研究环状发电机和与某些扩展相关的关系确定的。作为推论，确定了此类模块之间的模块化扩展组$ ext^1 $。
This paper concerns representations of the integral general linear group. The extension groups $Ext^2$ between any pair of hook Weyl modules are determined via a detailed study of cyclic generators and relations associated to certain extensions. As a corollary, the modular extension groups $Ext^1$ between such modules are determined.
