For a non-singular projective toric variety , the virtual logarithmic Tevelev degrees are defined as the virtual degree of the morphism from the moduli stack of logarithmic stable maps to the product . In this paper, after proving that Mikhalkin's correspondence theorem holds in genus 0 for logarithmic virtual Tevelev degrees, we use tropical methods to provide closed formulas for the case in which is a Hirzebruch surface. In order to do so, we explicitly list all the tropical curves contributing to the count.

Hirzebruch 表面的属 0 对数和热带固定域计数
对于非奇异射影复曲面簇,虚对数 Tevelev 度定义为来自对数稳定映射的模堆栈的态射的虚拟度到产品。在本文中,在证明米哈尔金对应定理在对数虚拟Tevelev度的属0中成立后,我们使用热带方法提供了以下情况的封闭公式:是 Hirzebruch 曲面。为此,我们明确列出了对计数有贡献的所有热带曲线。
