一般线性群的增强伴随作用及其轨道

Enhanced adjoint action and their orbits for the general linear group

Kyo Nishiyama, Takuya Ohta

摘要:

研究了一般线性群在其李代数与由若干个定义表示及其子代数组成的向量空间的乘积上的增强伴随作用。我们确定了正则半单轨道(即,最大维数的闭轨道)和增强零锥的结构,包括它的不可约分量及其维数。

英文摘要:

We studied an enhanced adjoint action of the general linear group on a product of its Lie algebra and a vector space consisting of several copies of defining representations and its duals. We determined regular semisimple orbits (i.e., closed orbits of maximal dimension) and the structure of enhanced null cone, including its irreducible components and their dimensions.
