涡方程模空间的体积与局部化

Volume of Moduli Space of Vortex Equations and Localization

Akiko Miyake, Kazutoshi Ohta, Norisuke Sakai

摘要:

利用Moore,Nekrasov和Shatashvili提出的拓扑场论和局部化技术,计算了紧致Riemann曲面上BPS涡的模空间的体积.我们将这种技术应用到阿贝尔(ANO)涡,并表明,模空间的体积同意与以前的结果,通过积分的模空间度量。我们扩展到非阿贝尔规范群和多口味的评价。我们还比较了我们的结果与体积的Kahler商空间的启发膜配置。

英文摘要:

We evaluate volume of moduli space of BPS vortices on a compact Riemann surface by using topological field theory and localization technique developed by Moore, Nekrasov and Shatashvili. We apply this technique to Abelian (ANO) vortex and show that the volume of moduli space agrees with the previous results obtained by integrating over the moduli space metric. We extend the evaluation to non-Abelian gauge groups and multi-flavors. We also compare our results with the volume of the Kahler quotient space inspired by the brane configuration.
