Let X be a smooth, irreducible, projective curve over an algebraically closed field of characteristic 0 and let g = gx ̂ 2 be its genus. We show in this paper that a generic vector b ndle on X of rank n and any fixed degree can be obtained s the direct image of a line b ndle on an n-sheeted (ramified) covering of X. From this we deduce results concerning linear Systems on the moduli space of vector bundles of rank n and degree 0. 
A note on theta divisors of stable bundles
Let C be a smooth complex irreducible projective curve of genus g≥3. We show that if C is a Petri curve with g≥4, a general stable vector bundle E on C, with integer slope, admits an irreducible and
