Ganatra-Pomerleano's cyclic coordinate-function conjecture

Let QQ be a closed, oriented 33-manifold. A cyclic coordinate function on a Liouville manifold MM is a pair (c~,ϕ~)SHS11(M)×SHS11(M)(\tilde{c},\tilde{\phi})\in\mathit{SH}_{S^1}^1(M)\times\mathit{SH}_{S^1}^1(M) satisfying

{c~,ϕ~}=1.\{\tilde{c},\tilde{\phi}\}=1.

Cyclic coordinate-function conjecture. If TQT^*Q admits a cyclic coordinate function, then QQ is diffeomorphic to S1×ΣgS^1\times\Sigma_g, where g0g\geq0, or a spherical space form. The source gives evidence for this expectation via the analogous coordinate-function conjecture, but no resolution is given.
