Automorphismes naturels de l'espace de Douady de points sur une surface

Algebraic Geometry 2009-05-28 v1

Abstract

We prove some general results concerning the size of the group of automorphisms of the Douady space of points on a surface. We then study some properties of the automorphisms coming from an automorphism of the surface, in particular their action on the cohomology and the classification of their fixed points.
