环面非交换流形上瞬子的模空间

Moduli Spaces of Instantons on Toric Noncommutative Manifolds

Simon Brain, Giovanni Landi, Walter D. van Suijlekom

摘要:

本文研究复曲面非对易流形$M_θ$上U(n)规范理论的解析性质。本文分析了四维流形$M_θ$上U(2)向量丛上的自对偶Yang-Mills方程解的模空间,证明了每个这样的模空间要么是空的,要么是一个光滑的Hausdorff流形,其维数是我们明确计算的.在四球$S^4_θ$的特殊情况下,我们发现具有固定第二陈数$k$的U(2)瞬子的模空间是维数为$8k-3$的光滑流形.

英文摘要:

We study analytic aspects of U(n) gauge theory over a toric noncommutative manifold $M_θ$. We analyse moduli spaces of solutions to the self-dual Yang-Mills equations on U(2) vector bundles over four-manifolds $M_θ$, showing that each such moduli space is either empty or a smooth Hausdorff manifold whose dimension we explicitly compute. In the special case of the four-sphere $S^4_θ$ we find that the moduli space of U(2) instantons with fixed second Chern number $k$ is a smooth manifold of dimension $8k-3$.
