我们给出了Nekrasov猜想的一个数学上严格的证明:在1 - 4上的实例模空间上的等变上同调的积分给出了n =2 SUSY Yang-Mills理论的Seiberg-Witten预势形式的一个变形。通过研究在算子上的模空间,导出了涅克拉索夫配分函数的微分方程。它是Seiberg-Witten预电位方程的变形,由Losev等人发现,并由Gorsky等人进一步研究。
We give a mathematically rigorous proof of Nekrasov’s conjecture: the integration in the equivariant cohomology over the moduli spaces of instantons on ℝ4gives a deformation of the Seiberg-Witten prepotential forN=2 SUSY Yang-Mills theory. Through a study of moduli spaces on the blowup of ℝ4, we derive a differential equation for the Nekrasov’s partition function. It is a deformation of the equation for the Seiberg-Witten prepotential, found by Losev et al., and further studied by Gorsky et al.
