The domination conjecture for perturbative PSU(n)-invariants

From papers

Let MM be a rational homology 3-sphere, let τPSU(n)(M)\tau^{PSU(n)}(M) denote its perturbative PSU(n)PSU(n)-invariant, and let τrSU(n)(M)\tau_r^{SU(n)}(M) denote the quantum invariant at a positive integer level rr.

Domination conjecture. The perturbative invariant τPSU(n)(M)\tau^{PSU(n)}(M) dominates the quantum invariants τrSU(n)(M)\tau_r^{SU(n)}(M) for every positive integer rr, not necessarily prime.

The preceding theorem recovers the quantum invariant through the perturbative invariant after applying the reduction map for sufficiently large primes. This conjecture asks for the corresponding domination for all positive integer levels, including nonprime levels; the source gives no resolution.
