关于内禀负曲线

On intrinsic negative curves

Antonio Laface, Luca Ugaglia

摘要:

设$\mathbb K$是特征$0$的代数闭域.由二元Laurent多项式生成的$(\mathbb K^*)^2$的曲线是{ \em内禀负},如果它的热带紧化有负自交.本说明的目的是开始系统地研究这些曲线,并将它们与复曲面的Seshadri常数计算问题联系起来。

英文摘要:

Let $\mathbb K$ be an algebraically closed field of characteristic $0$. A curve of $(\mathbb K^*)^2$ arising from a Laurent polynomial in two variables is {\em intrinsic negative} if its tropical compactification has negative self-intersection. The aim of this note is to start a systematic study of these curves and to relate them with the problem of computing Seshadri constants of toric surfaces.
