Automorphisms of singular three-dimensional cubic hypersurfaces

Algebraic Geometry 2018-11-21 v2

Abstract

In this paper we classify three-dimensional singular cubic hypersurfaces with an action of a finite group GG, which are not GG-rational, are not GG-birationally isomorphic to a quadric and have no birational structure of GG-Mori fiber space with the base of positive dimension. Also we prove the A5A_{5} -birational superrigidity of the Segre cubic.
