An infinite family of tight triangulations of manifolds

Published: 01 November 2013 Publication History

Abstract

We give explicit construction of vertex-transitive tight triangulations of d-manifolds for d>=2. More explicitly, for each d>=2, we construct two (d^2+5d+5)-vertex neighborly triangulated d-manifolds whose vertex-links are stacked spheres. The only other non-trivial series of such tight triangulated manifolds currently known is the series of non-simply connected triangulated d-manifolds with 2d+3 vertices constructed by Kuhnel. The manifolds we construct are strongly minimal. For d>=3, they are also tight neighborly as defined by Lutz, Sulanke and Swartz. Like Kuhnel@?s complexes, our manifolds are orientable in even dimensions and non-orientable in odd dimensions.
