Abstract:

A group with a cyclically symmetric presentation admits an automorphism of finite order called the shift. In this talk we look at families of cyclic group presentations that support symmetric three-manifold pairings and we show that these pairings give rise to non-identity fixed points for the shift on the fundamental group of the three-manifold.
