Parabolic generating pairs of genus-one 2-bridge knot groups

Group Theory 2015-09-30 v3 Geometric Topology

Abstract

We show that any parabolic generating pair of a genus-one hyperbolic 2-bridge knot group is equivalent to the upper or lower meridian pair. As an application, we obtain a complete classification of the epimorphisms from 2-bridge knot groups to genus-one hyperbolic 2-bridge knot groups.
