Abstract.
Deformations of cones over projective varieties have been studied by many people. In particular, Pinkham proved that a cone over an elliptic curve is smoothable if and only if it is contained in a smooth del Pezzo surface. In this talk, I will talk about the analogue of this result for cones over K3 surfaces.
