Smoothing cones over K3 surfaces
Résumé
We prove that the affine cone over a general primitively polarised K3 surface of genus g is smoothable if and only if g ≤ 10 or g = 12. We discuss connections with the classification of Fano threefolds, and several examples of singularities with special behaviour.
