Abstract
Let X be a geometrically irreducible smooth projective curve defined over a field k, and let E be a vector bundle on X. Then E is semistable if and only if there is a vector bundle F on X such that Hi(X,F⊗ E)=0 for i=0,1. We give an explicit bound for the rank of F. The proof uses a result of Popa for the case where k is algebraically closed.
