A universal non-embedding theorem for 3-manifolds

Geometric Topology 2026-04-27 v1

Abstract

We prove that given two compact oriented 33-manifolds NN and M,M, with MM satisfying only a mild hypothesis, there is a hyperbolic 33-manifold NN' arbitrarily ``closely related'' to N,N, and such that NN' does not embed in M.M. For instance, as a weak version of our main theorem, if MM is a rational homology sphere then for any k1k\geq 1 the 33-manifold NN' can be chosen to be YkY_k-equivalent to N.N. Our techniques rely on the construction of 33-manifolds with complicated Frohman--Kania-Bartoszy\'nska ideals, using the strong approximation for SO3\mathrm{SO}_3-Witten-Reshetikhin-Turaev quantum representations of mapping class groups of surfaces.
