有理曲线的变形虫刺
Spines for amoebas of rational curves
摘要：
对于每一条有理复曲线$C \subset (\mathbf{C}^\times)^n$，我们关联一条有理回归曲线$Γ\subset \mathbf{R}^n$，使得$C$的变形虫$\mathcal{A}(C) \subset \mathbf{R}^n$在距离$Γ$有界的距离内。根据Passare和Rullgård介绍的术语，我们将$Γ$称为$\mathcal{A}(C)$的主干。我们用样条来描述有理复曲线序列的热带极限。
英文摘要：
To every rational complex curve $C \subset (\mathbf{C}^\times)^n$ we associate a rational tropical curve $Γ\subset \mathbf{R}^n$ so that the amoeba $\mathcal{A}(C) \subset \mathbf{R}^n$ of $C$ is within a bounded distance from $Γ$. In accordance with the terminology introduced by Passare and Rullgård, we call $Γ$ the spine of $\mathcal{A}(C)$. We use spines to describe tropical limits of sequences of rational complex curves.
