本文将流形M上丛上的联络路所对应的Chern-Simons形式的等变扩张引入到自由圈空间LM中,并证明了它决定了丛上联络集上的一个等价关系.我们用它来定义一个环,回路微分K-理论的M,在很大程度上相同的方式,微分K-理论可以定义使用陈-西蒙斯形式[SS]。我们发现循环微分K-理论产生了一个改进的微分K-理论,特别是将完整信息纳入其类。此外,回路微分K-理论被证明是严格粗糙的Grothendieck群的丛连接到规范等价。最后,我们计算了圆的圈微分K-理论。
In this paper we introduce an equivariant extension of the Chern-Simons form, associated to a path of connections on a bundle over a manifold M, to the free loop space LM, and show it determines an equivalence relation on the set of connections on a bundle. We use this to define a ring, loop differential K-theory of M, in much the same way that differential K-theory can be defined using the Chern-Simons form [SS]. We show loop differential K-theory yields a refinement of differential K-theory, and in particular incorporates holonomy information into its classes. Additionally, loop differential K-theory is shown to be strictly coarser than the Grothendieck group of bundles with connection up to gauge equivalence. Finally, we calculate loop differential K-theory of the circle.
