A $P$-Adic Spectral Triple

Operator Algebras 2015-06-19 v2

Abstract

We construct a spectral triple for the C^*-algebra of continuous functions on the space of pp-adic integers by using a rooted tree obtained from coarse-grained approximation of the space, and the forward derivative on the tree. Additionally, we verify that our spectral triple satisfies the properties of a compact spectral metric space, and we show that the metric on the space of pp-adic integers induced by the spectral triple is equivalent to the usual pp-adic metric.
