关于全纯辛流形的自同构和双有理变换的注记

A note on automorphisms and birational transformations of holomorphic symplectic manifolds

Samuel Boissiere, Alessandra Sarti

摘要:

本文给出了K3曲面上点的Hilbert格式的自同构由曲面的自同构诱导的一个充要条件。进一步证明了射影不可约全纯辛流形的双有理变换群是双有理生成的。

英文摘要:

We give a necessary and sufficient condition for an automorphism of the Hilbert scheme of points on a K3 surface (non necessarily algebraic) to be induced by an automorphism of the surface. We prove furthermore that the group of birational transformations of a projective irreducible holomorphic symplectic manifold is finitely generated.
