Odaka's non-compact Yau–Tian–Donaldson conjecture
Let be a polarized dlt log Calabi–Yau pair with , , and ample on . Non-compact Yau–Tian–Donaldson conjecture. (1) If admits a complete Ricci-flat weak Kähler metric whose volume growth dimension is at most and whose Kähler class is , then is weakly open K-polystable. (2) Such a metric, with any base point, is the pointed Gromov–Hausdorff limit of conical singular weak cscK metrics on polarized dlt log Calabi–Yau compactifications as , with , if and only if is strongly open K-polystable. This is proposed as a metric-existence and correspondence principle; the source gives no resolution.
