摘要翻译:
我们用一种优雅的组合几何方法得到了关于剪接商奇点的一个新的重要的基本结果:函数环的除数滤子的每一层都是由定义坐标函数的单项式生成的。优雅的方法是基于Okuma对泛阿贝尔覆盖的函数环的描述的线束语言。作为一个简单的应用,我们得到了Neumann和Wahl的端曲线定理的一个新的证明。

英文摘要:
We obtain a new important basic result on splice-quotient singularities in an elegant combinatorial-geometric way: every level of the divisorial filtration of the ring of functions is generated by monomials of the defining coordinate functions. The elegant way is the language of of line bundles based on Okuma's description of the function ring of the universal abelian cover. As an easy application, we obtain a new proof of the End Curve Theorem of Neumann and Wahl.
