摘要:

利用拓扑场论和局部化技术计算了紧致亏格h型Riemann曲面Sigma_h上BPS涡的模空间的体积。本文首先研究了单荷标量场阿贝尔规范理论中的涡旋(ANO涡旋),发现其模空间的体积与以前在模空间度规上积分得到的结果更为直接地一致。接下来,我们扩展到非阿贝尔规范群和多口味的标量场的基本表示的评估。我们发现,本地化的结果可以一致地理解的模矩阵形式主义在任何可能的。更多的细节可以在我们的论文Prog.Theor.Phys.126(2011)637中找到。

英文摘要:

Volume of moduli space of BPS vortices on a compact genus h Riemann surface Sigma_h is evaluated by means of topological field theory and localization technique. Vortex in Abelian gauge theory with a single charged scalar field (ANO vortex) is studied first and is found that the volume of the moduli space agrees with the previous results obtained more directly by integrating over the moduli space metric. Next we extend the evaluation to non-Abelian gauge groups and multi-flavors of scalar fields in the fundamental representation. We find that the result of localization can be consistently understood in terms of moduli matrix formalism wherever possible. More details are found in our paper in Prog.Theor.Phys.126 (2011) 637.
