论文摘要
我们启动了牛顿 - 科恩科夫（Newton-Okounkov）功能在感谢您的品种上的组合研究，并着眼于线束束的渐近不变的合理性。在我们的努力过程中，我们确定了一种组合条件，可确保在感谢您的表面上适当的牛顿 - 科恩科夫功能的受控行为。我们的方法产生了以前未解决的许多Seshadri常数的合理性。
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.
