论文摘要
本文涉及Coxeter组亚组的实现问题。我们构建了Coxeter组的亚组$ g $ $ w_ {15} $，以便将$ g $实现为有理表面$ x $和$ g \ g \ cong aut（x）^* \ cong d_3 \ times \ times \ times \ mathbb {z} $的$ g $。我们还表明，$ w_ {14} $中有一个元素$ω$无法实现。
This article concerns the realization problem of subgroups of Coxeter groups. We construct a subgroup $G$ of the Coxeter group $W_{15}$ such that $G$ is realized as automorphism groups of a rational surface $X$ and $G \cong Aut(X)^* \cong D_3 \times \mathbb{Z}$. We also show that there is an element $ω$ in $W_{14}$ is not realizable.
