Conjugacy classes of special automorphisms of the affine spaces
Jérémy Blanc
In the group of polynomial automorphisms of the plane, the conjugacy class of an element is closed if and only if the element is diagonalisable. In this article, we show that this…
On birational maps from cubic threefolds
Jérémy Blanc, Stéphane Lamy
We characterise smooth curves in a smooth cubic threefold whose blow-ups produce a weak-Fano threefold. These are curves of genus and degree , such that (i) $2(d-5) \le…
Algebraic elements of the Cremona groups
Jérémy Blanc
This article studies algebraic elements of the Cremona group. In particular, we show that the set of all these elements is a countable union of closed subsets but it is not closed.
The group of Cremona transformations generated by linear maps and the standard involution
Jérémy Blanc, Isac Hedén
This article studies the group generated by automorphisms of the projective space of dimension and by the standard birational involution of degree . Every element of this gr…
