给出了格Wilson-Dirac算子的指数定理的一个证明,证明了标准环面上的扭曲Dirac算子的指数可以用相应的格Wilson-Dirac算子来描述.我们的证明是基于几乎平坦向量丛的高指标理论。
We give a proof of the index theorem of lattice Wilson–Dirac operators, which states that the index of a twisted Dirac operator on the standard torus is described in terms of the corresponding lattice Wilson–Dirac operator. Our proof is based on the higher index theory of almost flat vector bundles.
