Ribbon cobordisms as a partial order

Geometric Topology 2025-10-23 v3

Abstract

We show that the notion of ribbon rational homology cobordism yields a partial order on the set of aspherical 33-manifolds, thus supporting a conjecture formulated by Daemi, Lidman, Vela-Vick and Wong. Our proof is built on Agol's recent proof of the fact that ribbon concordance yields a partial order on the set of knots in the 3-sphere.
