Dunfield's orderability conjecture for Dehn fillings
Dunfield's orderability conjecture for Dehn fillings
Let be a hyperbolic -homology solid torus, and let denote its longitudinal filling. Assume that is hyperbolic and that its holonomy representation has trace field with a real embedding at which the associated quaternion algebra splits. A Dehn filling is called orderable when its fundamental group is left-orderable. Dunfield's conjecture. Every Dehn filling with rational in an interval is orderable. The conjecture concerns orderability near the longitudinal filling under an arithmetic splitting hypothesis; the source does not specify whether it has been resolved.
