Title |
Cylinders in del Pezzo surfaces |
Abstract |
Let (X,H) be a ample polarization of a projective variety X. An H-polar cylinder in X is an open affine cylinder-like set whose complement is a support of an effective Q-divisor Q-rationally equivalent to H. This notion relates affine, birational and Kaehler geometry. we will show how to construct cylinders and to prove non-existence of them in smooth and mildly singular del Pezzo surfaces This is an extended answer of an question of Zaidenberg and Flenner in 2003. This is a joint work with I.Cheltsov and J.Park. |
