Fecha: | 2008 |
Resumen: | 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. |
