实曲线和热带平面曲线的拐点

Inflection Points of Real and Tropical Plane Curves

Erwan Brugallé, Lucía López de Medrano

摘要:

我们证明,Viro的拼接产生真正的代数曲线的最大数量的真正的拐点。特别地,这意味着最大弯曲的实代数$M$ -曲线实现许多合痕类型。本文采用的策略是热带的:研究经典平面代数曲线的拐点的热带极限。我们用来理解这些热带拐点的主要热带工具是热带变化。

英文摘要:

We prove that Viro's patchworking produces real algebraic curves with the maximal number of real inflection points. In particular this implies that maximally inflected real algebraic $M$-curves realize many isotopy types. The strategy we adopt in this paper is tropical: we study tropical limits of inflection points of classical plane algebraic curves. The main tropical tool we use to understand these tropical inflection points are tropical modifications.
