Calabi-Yau三重不变量的Gromov-Witten、Gopakumar-Vafa和Donaldson-Thomas不变量

Gromov-Witten, Gopakumar-Vafa, and Donaldson-Thomas invariants of Calabi-Yau threefolds

Sheldon Katz

摘要:

比较了Calabi-Yau三重不变量的Gromov-Witten、Gopakumar-Vafa和Donaldson-Thomas不变量。在某些情况下,唐纳森-托马斯不变量非常容易处理,有时比其他不变量更容易。这一点是说明在几个方面,特别是通过重新计算Gopakumar-Vafa不变量的卡茨,Klemm,和Vafa在一个严格的数学框架。这篇笔记是基于我在2004年Snowbird弦几何会议上的演讲。

英文摘要:

Gromov-Witten, Gopakumar-Vafa, and Donaldson-Thomas invariants of Calabi-Yau threefolds are compared. In certain situations, the Donaldson-Thomas invariants are very easy to handle, sometimes easier than the other invariants. This point is illustrated in several ways, especially by revisiting computations of Gopakumar-Vafa invariants by Katz, Klemm, and Vafa in a rigorous mathematical framework. This note is based on my talk at the 2004 Snowbird Conference on String Geometry.
