Espaces twistoriels et structures complexes non standards
Deschamps, Guillaume (Université de Bretagne Occidentale)

Data:	2008
Resum:	In this article we use the twistor theory in order to build "non standard" complex structures (with a meaning which we define) on the products of 4-manifolds with the sphere of dimension two. To that end, we enumerate the set of complex surfaces whose twistor space is C∞-trivial. Among these surface we will study those which admit an anti-self-dual riemannian metric.
