Structures affines et projectives sur les surfaces complexes

A complex affine (resp. projective) structure on a complex surface is an atlas of charts with value in 2 (resp. in P 2 ) with change of coordinates in the affine group A(2,) (resp. PGL(3,)). In this paper we classify the affine complex surfaces and calculate, given a complex surface S, the space of deformation of affine structures on S compatible with its analytic structure. We also show that a projective structure on a complex surface admitting an affine structure is necessarily affine.

Une structure complexe affine (resp. projective) sur une surface complexe est la donnée d’un atlas de cartes à valeur dans 2 (resp. P 2 ) à changements de cartes localement constants dans le groupe affine A(2,) (resp. le groupe PGL(3,)). Dans cet article nous classifions les surfaces complexes affines et calculons, à surface complexe S fixée, l’espace de déformation des structures complexes affines sur S compatibles avec sa structure analytique. Nous montrons aussi que toute structure projective sur une surface complexe admettant une structure complexe affine est nécessairement affine.
