The Local Index Formula in Noncommutative Geometry
摘要
In this chapterLocal index formula we present a proof of the Connes–Moscovici index formula, expressing the index of a (twisted) operator D in a spectral tripleSpectral triple \((\mathcal {A},\mathcal {H},D)\) by a local formula. First, we illustrate the contents of this chapter in the context of two examples in the odd and even case: the index on the circle and on the torus.
