Birational automorphisms of double spaces with singularities
Journal of Mathematical Sciences, 1997The author studies a particular class of algebraic varieties. They are two-sheeted covers of a projective space \(\mathbb P^m \) (\(m>2\)) over an algebraically closed field, with some restrictions on the set over which these covers are branched. The main theorem is that these varieties are birationally super-rigid.

On birational automorphisms of a three-dimensional cubic
Russian Mathematical Surveys, 1984The author describes necessary conditions that must be satisfied by the generators of the group of birational automorphisms of a three- dimensional cubic. The conditions are described with respect to the ''maximal singularity'' of an automorphism of a three-dimensional cubic. The author shows that all the conditions described are effectively realised.

BIRATIONAL AUTOMORPHISMS OF A DOUBLE SPACE AND DOUBLE QUADRIC
Mathematics of the USSR-Izvestiya, 1989It is proved that the groups of birational automorphisms are the same as the groups of biregular automorphisms for two series of Fano varieties of dimension 4 and higher: double spaces of index 1 and double quadrics of index 1. From this it follows that the varieties are not rational.

Birational automorphisms of algebraic threefolds fibred by cubic surfaces
Russian Mathematical Surveys, 1997Let \(V\) be a smooth three-dimensional complex projective variety having a morphism \(\pi:V\to \mathbb P^1\), each fibre of which is an irreducible reduced cubic surface, and the generic fibre \(F_{\mu}\) is a smooth cubic surface over \(\mathbb C(\mathbb P^1)\) with Picard group \(\text{Pic}(F_{\mu})=\mathbb ZK_{F_{\mu}}.\) The paper under review ...
