Equidistribution of elements of norm 1 in cyclic extensions

Authors: Kathleen L. Petersen and Christopher D. Sinclair

Abstract:

Upon quotienting by units, the elements of norm 1 in a number field $K$ form a countable subset of a torus of dimension $r_1 + r_2 - 1$, where $r_1$ and $r_2$ are the numbers of real and pairs of complex embeddings. When $K$ is Galois with cyclic Galois group we demonstrate that this countable set is equidistributed in a finite cover of this torus with respect to a natural partial ordering induced by Hilbert's Theorem 90.

Keywords: equidistribution, cyclic number field, Hecke zeta function, norm 1
