Finite quasisimple groups acting on rationally connected threefolds

Jérémy Blanc, Ivan Cheltsov, Alexander Duncan +1

We show that the only finite quasi-simple non-abelian groups that can faithfully act on rationally connected threefolds are the following groups: , $\operatorname{P…

Delta invariants of singular del Pezzo surfaces

Ivan Cheltsov, Jihun Park, Constantin Shramov

We estimate -invariants of some singular del Pezzo surfaces with quotient singularities, which we studied ten years ago. As a result, we show that each of these surfaces admits…

Delta invariants of smooth cubic surfaces

Ivan Cheltsov, Kewei Zhang

We prove that -invariants of smooth cubic surfaces are at least .
