论文摘要
我们考虑了A. King介绍的基本变化组的最大紧凑型亚组的基本变化作用以及is砂空间的实际或复杂表示空间以及相关的动量图。我们根据遗传操作员的特征值递归定义的不平等现象,对动量图图像进行明确描述。此外,我们表征了何时最大的动量图图像,分别为正体积。
We consider the base change action on real or complex representation spaces of quivers and the associated momentum map for a maximal compact subgroup of the base change group, as introduced by A. King. We give an explicit description of the momentum map image in terms of recursively defined inequalities on eigenvalues of Hermitian operators. Moreover, we characterize when the momentum map image is maximal possible, respectively of positive volume.
