通过引入5D Chern-Simons项的影响，我们推广了Nekrasov提出的5D纯U（N）超Yang-Mills的重力光子修正前势.这种推广使我们能够通过规范理论计算再现局部复曲面Calabi-Yau流形XmN上相应拓扑A模型的配分函数，其中m = 0，1，. N.最初的建议对应于m = 0的情况。
We extend the graviphoton-corrected prepotential of 5D pure U(N) super Yang-Mills, which was originally proposed by Nekrasov, by incorporating the effect of the 5D Chern-Simons term. This extension allows us to reproduce by a gauge theory calculation the partition functions of corresponding topological A-model on local toric Calabi-Yau manifolds XmN for all m = 0,1,...,N. The original proposal corresponds to the case m = 0.
