Ribbon concordance of knots is a partial order

Geometric Topology 2022-01-12 v1

Abstract

In this note we show that ribbon concordance forms a partial ordering on the set of knots, answering a question of Gordon. The proof makes use of representation varieties of the knot groups to SO(N)SO(N) and relations between them induced by a ribbon concordance.
