Turaev–Viro commensurability conjecture for geometric 3-manifolds

Let MM and NN be closed irreducible geometric 3-manifolds. Their abelian and SU(2)SU(2) Turaev–Viro invariants are the collections of invariants associated to abelian and SU(2)SU(2) theories, respectively. Turaev–Viro commensurability conjecture. If MM and NN have the same abelian and SU(2)SU(2) Turaev–Viro invariants, then MM and NN should be commensurable and, in particular, share the same geometry.

The conjecture is motivated by the preceding results for torus bundles, where these invariants impose strong arithmetic restrictions, but the general statement is left open.
