Common stabilizations of Heegaard splittings of knot exteriors

Abstract

In [4], we gave a condition for a pair of unknotting tunnels of a non-trivial tunnel number one link to give a genus three Heegaard splitting of the link complement. In this paper we prove the corresponding result for tunnel number one knots.

Keywords: Heegaard splitting, stabilization, unknotting tunnel
