Let A' be a smooth complex projective curve of genus g over an algebraically closed field k of charcteristic 0. In this paper we prove that given two general stable bundles F and G such that

We propose a new method of classifying vector bundles on projective curves, especially singular ones, according to their "representation type." In particular, we prove that the classification problem of vector bundles, respectively of torsion-free sheaves, on projective curves is always finite, tame

## Abstract In this paper we consider the singularities of the varieties parameterizing stable vector bundles of fixed rank and degree with sections on a smooth curve of genus at least two. In particular, we extend results of Y. Laszlo, and of the second author, regarding the singularities of gener
