Generalized uniqueness conjecture for compatible Calabi–Yau metrics
Generalized uniqueness conjecture for compatible Calabi–Yau metrics
Fix a polystable negative valuation on . Let be the space of compatible Calabi–Yau metrics on with , let be the corresponding weighted asymptotic cone, and let be the space of Calabi–Yau cone metrics on with the Reeb vector field determined by . Consider the map
obtained by taking the appropriate rescaled limit of the Kähler form under the weighted asymptotic cone construction. Generalized uniqueness conjecture. The map is well-defined and bijective. This would identify compatible Calabi–Yau metrics with their asymptotic cone metrics and extend uniqueness beyond the uniform-equivalence question; it remains open.
