Birational Geometry of sextic del Pezzo surfaces
Elias Kurz, Egor Yasinsky
We study the biregular and birational geometry of degree 6 del Pezzo surfaces with Picard number 1, defined over an arbitrary perfect field. Using Galois cohomology techniques, we…

On -birational rigidity of del Pezzo surfaces
Egor Yasinsky
Let be a finite group and be its subgroup. We prove that if a smooth del Pezzo surface over an algebraically closed field is -birationally rigid then it is al…

Linearization problem for finite subgroups of the plane Cremona group
Antoine Pinardin, Arman Sarikyan, Egor Yasinsky
We give a complete solution of the linearization problem in the plane Cremona group over an algebraically closed field of characteristic zero.
