AbstractLet f : X. B be a generic ordinary proper fibration over a complete curve in positive characteristics, we prove that the dual of higher direct image sheaf R1f similar to O X is nef. As a corollary, we show that f similar to!S=B is nef, if f : S. B is a fibration from a surface to a curve with generic ordinary fibres.
