Complements of hypersurfaces in projective spaces
Jérémy Blanc, Pierre-Marie Poloni, Immanuel Van Santen
We study the complement problem in projective spaces over any algebraically closed field: If are irreducible hypersurfaces of degree $…
Birational maps of Severi-Brauer surfaces, with applications to Cremona groups of higher rank
Jérémy Blanc, Julia Schneider, Egor Yasinsky
We prove that any group of cardinality at most the one of is a quotient of any Cremona group of rank at least . This provides a definitive answer to the question of…
Real forms of some Gizatullin surfaces and Koras-Russell threefolds
Jérémy Blanc, Anna Bot, Pierre-Marie Poloni
We describe the real forms of Gizatullin surfaces of the form and of Koras-Russell threefolds of the first kind. The former admit zero, two, three, four or six isomorphis…
Abelian varieties as automorphism groups of smooth projective varieties in arbitrary characteristics
Jérémy Blanc, Michel Brion
Let be an abelian variety over an algebraically closed field. We show that is the automorphism group scheme of some smooth projective variety if and only if has only fi…
Connected algebraic groups acting on Fano fibrations over
Jérémy Blanc, Enrica Floris
Let be a Mori fibre space with general fibre of Picard rank at least two. We prove that there is a proper closed subset , invariant by the connected…
Bivariables and Vénéreau polynomials
Jérémy Blanc, Pierre-Marie Poloni
We study a family of polynomials introduced by Daigle and Freudenburg, which contains the famous Vénéreau polynomials and defines -fibrations over . Acc…
