On G-birational rigidity of del Pezzo surfaces
Abstract
Let G be a finite group and H⊂eq G be its subgroup. We prove that if a smooth del Pezzo surface over an algebraically closed field is H-birationally rigid then it is also G-birationally rigid, answering a geometric version of Kollár's question in dimension 2 by positive.
