摘要:

作者主要研究有限Coxeter群的Gröbner-Shirshov基。已知有限Coxeter群通过Coxeter-Dynkin图分类。在固定顺序下,群的呈现决定了群的Gröbner-Shirshov基。本文中,作者重新排列生成元,将其标记在Coxeter-Dynkin图上,并获得了Coxeter群G₂,F₄,E₆和E₇的Gröbner-Shirshov基的简单表示。本文还给出了Coxeter群E₈的Gröbner-Shirshov基。

英文摘要:

The author is mainly interest in the Gröbner-Shirshov bases of finite Coxeter groups. It is known that the finite Coxeter groups are classified in terms of Coxeter-Dynkin diagrams. Under the fixed order, it is worth mention that the presentation of group determines the Gröbner-Shirshov bases of group. In this paper, the author rearranges the generators, marks them on Coxeter-Dynkin diagrams, and gets a simple presentation of the Gröbner-Shirshov bases for Coxeter groups of types $G_2, F_4, E_6$ and $E_7$. This article also gives the Gröbner-Shirshov basis of Coxeter group of type $E_8$.
