Kontsevich模空间的稳定基轨迹分解

Stable Base Locus Decompositions of Kontsevich Moduli Spaces

Dawei Chen, Izzet Coskun

摘要:

本文确定了二次和三次稳定映射的Kontsevich模空间到Grassmannian的稳定基轨迹分解。这给出了新的例子分解的品种皮卡秩三。我们还讨论了双有理模型,对应于分解中的腔室。

英文摘要:

In this paper, we determine the stable base locus decomposition of the Kontsevich moduli spaces of degree two and three stable maps to Grassmannians. This gives new examples of the decomposition for varieties with Picard rank three. We also discuss the birational models that correspond to the chambers in the decomposition.
