AI总结:
本文研究E_7型简单奇点形变所对应的六参数曲面族,通过计算复反射群ST34的余秩1反射子群对应的单参数子族,确定了其中出现的简单奇点类型。
摘要:
本文研究C^3中的一族曲面,该族曲面是E_7型简单奇点的形变。该族具有六个参数,这些参数被视为Shephard和Todd论文列表[ST]中第34号复反射群的基本不变量。我们计算了所讨论的族中对应于第34号群的余秩为1的反射子群的单参数子族。特别地,我们确定了以这种方式出现的曲面上的简单奇点的类型。
英文摘要:
This paper studies a family of surfaces of ${\bf C}^3$ which is a deformation of a simple singularity of type $E_7$. This family has six parameters which are regarded as basic invariants of the complex reflection group No.34 in the list of the paper of Shephard and Todd \cite{ST}. We compute 1-parameter subfamilies of the family in question corresponding to corank one reflection subgroups of No.34 group. In particular, we determine the types of simple singularities on the surfaces appeared in this manner.
