The Gordian distance of handlebody-knots and Alexander biquandle colorings

Tomo Murao

Published 2017-04-25Version 1

We give lower bounds for the Gordian distance and the unknotting number of handlebody-knots by using Alexander biquandle colorings. We construct handlebody-knots with Gordian distance $n$ and unknotting number $n$ for any positive integer $n$.
