An algorithm for finding parameters of tunnels

Kai Ishihara

Algebraic & Geometric Topology 11 (2011) 2167–2190
Abstract

Cho and McCullough gave a numerical parameterization of the collection of all tunnels of all tunnel number 1 knots and links in the 3–sphere. Here we give an algorithm for finding the parameter of a given tunnel by using its Heegaard diagram.

Keywords
