Nombres de Betti des surfaces elliptiques r\'eelles
Abstract
We prove a new bound for the number of connected components of a real regular elliptic surface with a real section and we show the sharpness of this bound. Furthermore, all possible values for the Betti numbers of such a surface are realized.
