The Reidemeister spectrum of low dimensional almost-crystallographic groups

Abstract

We determine which non-crystallographic, almost-crystallographic groups of dimension 4 have the $R_{\infty }$-property. We then calculate the Reidemeister spectra of the 3-dimensional almost-crystallographic groups and the 4-dimensional almost-Bieberbach groups.
