On the cancellation problem for algebraic tori
Adrien Dubouloz
We address a variant of Zariski Cancellation Problem, asking whether two varieties which become isomorphic after taking their product with an algebraic torus are isomorphic themsel…
On rational additive group actions
Adrien Dubouloz, Alvaro Liendo
We characterize rational actions of the additive group on algebraic varieties defined over a field of characteristic zero in terms of a suitable integrability property of their ass…
Families of affine ruled surfaces: existence of cylinders
Adrien Dubouloz, Takashi Kishimoto
We show that the generic fiber of a family of smooth -ruled affine surfaces always carries an -fibration, possibly after a finite extension of the b…
Automorphisms of open surfaces with irreducible boundary
Adrien Dubouloz, Stéphane Lamy
Let (S, B) be the log pair associated with a projective completion of a smooth quasi-projective surface V . Under the assumption that the boundary B is irreducible, we obtain an al…
