Non-minimal bridge positions of torus knots are stabilized

Geometric Topology 2015-05-19 v1

Abstract

We show that any non-minimal bridge decomposition of a torus knot is stabilized and that nn-bridge decompositions of a torus knot are unique for any integer nn. This implies that a knot in a bridge position is a torus knot if and only if there exists a torus containing the knot such that it intersects the bridge sphere in two essential loops.
