GrÃ¶bner-Shirshov bases for the Coxeter groups of the types $G_{2}, F_{4}, E_{6}, E_{7}$ and $E_{8}$

Xiaowei Pang, Jun Wang

The author is mainly interest in the GrÃ¶bner-Shirshov bases of finite Coxeter groups. It is known that the finite Coxeter groups are classified in terms of Coxeter-Dynkin diagrams…

The multiple points of maps from sphere to Euclidean space

Jun Wang, Xuezhi Zhao

In this paper, we obtain some sufficient conditions to guarantee the existence of multiple points of maps from $S^{m}$ to $R^{d}$ . Our main tool is the ideal-valued index of $…
