Birational rigidity of a three-dimensional double cone
Mikhail Grinenko
It is proved that a three-dimensional double cone is a birationally rigid variety. We also compute the group of birational automorphisms of such a variety. This work is based on th…

Birational automorphisms of a three-dimensional double quadric with an elementary singularity
Mikhail Grinenko
It is proved that the group of birational automorphisms of a three-dimensional double quadric with a singular point arising from a double point on the branch divisor is a semidirec…

Normal surfaces with strictly nef anticanonical divisors
Mikhail Grinenko
In this paper we study normal surfaces whose anticanonical divisors are strictly nef, i.e. (-K)C>0 for every curve C.
