Let E be a vector bundle of rank r over an irreducible smooth projective curve X defined over the field . For fixed integers with , let be the corresponding flag bundle over X associated to E. Let be a line bundle such that for every pair of the form , where C is an irreducible smooth projective curve defined over and is a nonconstant morphism, the inequality holds. We prove that the line bundle is ample.
