摘要：
我们提出了一个新的处方计算Nekrasov配分函数的五维理论与八个超荷实现测量非微扰味对称性的三个五维超共形场论。拓扑顶点方法给出了味瞬子背景下物质理论的配分函数的计算方法，并通过在Young图上求和实现了配分函数的规范化.我们应用处方计算Nekrasov配分函数的各种五维规范理论，如$\mathrm{SO}(2N)$规范理论与或不超多重态的矢量表示，也纯$E_6, E_7, E_8$规范理论。此外，该技术可以应用于计算的Nekrasov配分函数的五维理论，产生的圆紧化的六维最小超共形场论的规范群$\mathrm{SU}(3), \mathrm{SO}(8), E_6, E_7, E_8$。我们通过比较一些得到的配分函数与已知的结果，发现我们的方法完美的协议。本文还提出了一种将粘合规则推广到加细拓扑顶点的方法。
英文摘要：
We propose a new prescription for computing the Nekrasov partition functions of five-dimensional theories with eight supercharges realized by gauging non-perturbative flavor symmetries of three five-dimensional superconformal field theories. The topological vertex formalism gives a way to compute the partition functions of the matter theories with flavor instanton backgrounds, and the gauging is achieved by summing over Young diagrams. We apply the prescription to calculate the Nekrasov partition functions of various five-dimensional gauge theories such as $\mathrm{SO}(2N)$ gauge theories with or without hypermultiplets in the vector representation and also pure $E_6, E_7, E_8$ gauge theories. Furthermore, the technique can be applied to computations of the Nekrasov partition functions of five-dimensional theories which arise from circle compactifications of six-dimensional minimal superconformal field theories characterized by the gauge groups $\mathrm{SU}(3), \mathrm{SO}(8), E_6, E_7, E_8$. We exemplify our method by comparing some of the obtained partition functions with known results and find perfect agreement. We also present a prescription of extending the gluing rule to the refined topological vertex.
