Characterizing slopes for the $(-2,3,7)$-pretzel knot

Geometric Topology 2022-09-23 v1

Abstract

In this note we exhibit concrete examples of characterizing slopes for the knot 12n24212n242, aka the (2,3,7)(-2,3,7)-pretzel knot. Although it was shown by Lackenby that every knot admits infinitely many characterizing slopes, the non-constructive nature of the proof means that there are very few hyperbolic knots for which explicit examples of characterizing slopes are known.
