有限Gelfand-Kirillov维数的点连通霍普夫代数的性质

Properties of pointed and connected Hopf algebras of finite Gelfand-Kirillov dimension

Guangbin Zhuang

摘要:

设$H$是点霍普夫代数.我们证明了在一些温和的假设下,$H$及其相关的分次霍普夫代数$\gr H$具有相同的Gelfand-Kirillov维数.作为应用,我们证明了连通霍普夫代数的Gelfand-Kirillov维数要么是无穷大,要么是正整数.我们还对特征为零的代数闭域上的GK-维3连通霍普夫代数进行了分类。

英文摘要:

Let $H$ be a pointed Hopf algebra. We show that under some mild assumptions $H$ and its associated graded Hopf algebra $\gr H$ have the same Gelfand-Kirillov dimension. As an application, we prove that the Gelfand-Kirillov dimension of a connected Hopf algebra is either infinity or a positive integer. We also classify connected Hopf algebras of GK-dimension three over an algebraically closed field of characteristic zero.
