Abstract

Abstract: The aim of this Note is to give some applications of twistor theory about existence or non-existence of complex structures. We slightly improve Yau''s result [Topology 15 (1976) 51–53] by giving the full list of compact parallelizable real 4-manifolds with a complex structure. On the other hand, we give a family of parallelizable 4-manifolds without complex structure but whose product with the sphere is complex. To cite this article: G. Deschamps, C. R. Acad. Sci. Paris, Ser. I 341 (2005). [Copyright &y& Elsevier]
