The Classification of Rigid Torus Quotients with Canonical Singularities in Dimension Three

Abstract

We provide a fine classification of rigid three-dimensional torus quotients with isolated canonical singularities, up to biholomorphism and diffeomorphism. This complements the classification of Calabi-Yau 3-folds of type $\rm{III}_0$, which are those quotients with Gorenstein singularities.
