| Abstract: | We prove a numerical characterization of ?n for varieties with at worst isolated local complete intersection quotient singularities. In dimension 3, we prove such a numerical characterization of ?3 for normal ?-Gorenstein projective varieties. |
| Keywords: | Deformation theory Deligne–Mumford stack ?-Gorenstein singularities |
