Abstract
In this paper we obtain bounds on where is a semistable bundle of rank 3 over a smooth irreducible projective curve of genus defined over an algebraically closed field of characteristic 0. These bounds are expressed in terms of the degrees of stability , . We show also that in some cases the bounds are best possible. These results extend recent work of J. Cilleruelo and I. Sols for bundles of rank 2.
