复曲面Newton-Okounkov函数及其在曲面上某些Seshadri常数的合理性中的应用

Toric Newton-Okounkov functions with an application to the rationality of certain Seshadri constants on surfaces

Christian Haase, Alex Küronya, Lena Walter

摘要:

本文从线丛的渐近不变量的合理性出发,对环面簇上的Newton-Okounkov函数进行了组合研究。在我们的努力过程中,我们确定了一个组合的条件,确保了适当的牛顿Okounkov函数的复曲面上的控制行为。我们的方法产生的合理性,许多Seshadri常数尚未解决之前。

英文摘要:

We initiate a combinatorial study of Newton-Okounkov functions on toric varieties with an eye on the rationality of asymptotic invariants of line bundles. In the course of our efforts we identify a combinatorial condition which ensures a controlled behavior of the appropriate Newton-Okounkov function on a toric surface. Our approach yields the rationality of many Seshadri constants that have not been settled before.
