Width of a satellite knot and its companion

Qilong Guo and Zhenkun Li

Algebraic & Geometric Topology 18 (2018) 1–13
Abstract

In this paper, we give a proof of a conjecture which says that w(K) n2w(J), where w( ) is the width of a knot, K is a satellite knot with J as its companion, and n is the winding number of the pattern. We also show that equality holds if K is a satellite knot with braid pattern.
