Toric簇上乘子理想次可加性的一个反例
A Counterexample for Subadditivity of Multiplier Ideals on Toric Varieties
摘要:
我们构造了一个3维完全交复曲面簇,在其上次可加性公式不成立,否定地回答了Takagi和Watanabe的一个问题。给出了二维正规环面簇的次可加性公式的组合证明。
英文摘要:
We construct a 3-dimensional complete intersection toric variety on which the subadditivity formula doesn't hold, answering negatively a question by Takagi and Watanabe. A combinatorial proof of the subadditivity formula on 2-dimensional normal toric varieties is also provided.
