High distance knots

arXiv:math/0607265 · doi:10.2140/agt.2007.7.1471

Abstract

We construct knots in S^3 with Heegaard splittings of arbitrarily high distance, in any genus. As an application, for any positive integers t and b we find a tunnel number t knot in the three-sphere which has no (t,b)-decomposition.
