A p-adic spectral triple

Abstract

dc:description.abstract

<p>We construct a spectral triple for the C*-algebra of continuous functions on the space of <em>p</em>-adic integers. On the technical level we utilize a weighted rooted tree obtained from a coarse grained approximation of the space combined with the forward derivative <em>D</em> on the tree. Our spectral triple satisfies the properties of a compact spectral metric space and the metric on the space of <em>p</em>-adic integers induced by the spectral triple is equivalent to the usual <em>p</em>-adic metric. Furthermore, we show that the spectrum of the operator <em>D*D </em>is closely related to the roots of a certain <em>q</em>-hypergeometric function and discuss the analytic continuation of the zeta function associated with <em>D*D.</em></p>
