Cylinders in singular del Pezzo surfaces
Ivan Cheltsov, Jihun Park, Joonyeong Won
For each del Pezzo surface with du Val singularities, we determine whether it admits a -polar cylinder or not. If it allows one, then we present an effective $\mathbb{Q…

Affine cones over smooth cubic surfaces
Ivan Cheltsov, Jihun Park, Joonyeong Won
We show that affine cones over smooth cubic surfaces do not admit non-trivial -actions.
