摘要
在本综述中,我总结了由赋值和 Gröbner 理论得到的环面退化的构造,并描述了它们在何种意义下等价。我展示了如何利用适配基将经典的牛顿多面体推广至所谓的 -牛顿多面体。该 -牛顿多面体决定了所有共享适配标准单项式基 的 Khovanskii-有限赋值的牛顿–Okounkov 多面体。

I wrote this survey for the Proceedings of the Nottingham Algebraic Geometry Seminar in 2021. I hope it serves as an overview or introduction to Toric Degenerations, it is especially addressed to students and non experts. Comments are very welcome
