六维箭图矩阵模型与拓扑配分函数

Quiver Matrix Model and Topological Partition Function in Six Dimensions

Hidetoshi Awata, Hiroaki Kanno

摘要:

本文考虑一个拓扑U(N)规范理论在D 6膜上的瞬子动力学的对偶描述的拓扑U(N)矩阵模型。该模型是导致Nekrasov的配分函数的ADHM矩阵模型的高维模拟。复曲面作用在模空间上的不动点用有色平面剖分来标记。假设局部化定理,我们计算的配分函数作为一个等变指数。结果表明,配分函数不依赖于在低能下使U(N)对称性破缺为U(1)^N的Higgs场的真空期望值。我们猜想了一个配分函数的一般公式,如果我们施加Calabi-Yau条件,它可以简化为MacMahon函数的幂。对于非Calabi-Yau情形,我们证明了该猜想的三阶瞬子展开。

英文摘要:

We consider a topological quiver matrix model which is expected to give a dual description of the instanton dynamics of topological U(N) gauge theory on D6 branes. The model is a higher dimensional analogue of the ADHM matrix model that leads to Nekrasov's partition function. The fixed points of the toric action on the moduli space are labeled by colored plane partitions. Assuming the localization theorem, we compute the partition function as an equivariant index. It turns out that the partition function does not depend on the vacuum expectation values of Higgs fields that break U(N) symmetry to U(1)^N at low energy. We conjecture a general formula of the partition function, which reduces to a power of the MacMahon function, if we impose the Calabi-Yau condition. For non Calabi-Yau case we prove the conjecture up to the third order in the instanton expansion.
