Pseudo complex volume uniqueness conjecture for hyperbolic Dehn fillings

About 7 years old · traced to

Let M\mathcal{M} be an nn-cusped hyperbolic 33-manifold with non-symmetric cusp shapes. Let NMC(v)N_{\mathcal{M}}^{\mathbb{C}}(v) denote the number of Dehn fillings of M\mathcal{M} whose pseudo complex volume is vv. Pseudo complex volume uniqueness conjecture. For every v∈Cv\in\mathbb{C} sufficiently close to vol⁡CM\operatorname{vol}_{\mathbb{C}}\mathcal{M} modulo iπ2Zi\pi^2\mathbb{Z}, one has

NMC(v)=1.N_{\mathcal{M}}^{\mathbb{C}}(v)=1.

The preceding theorem establishes uniqueness for sufficiently large filling coefficients; the conjecture asserts the corresponding local uniqueness near the complex volume of the unfilled manifold without explicitly imposing that coefficient bound.
