| Popis: | It is well known that there are no stable bundles of rank greater than 1 on the projective line. In this paper, our main purpose is to study the existence problem for stable coherent systems on the projective line when the number of sections is larger than the rank. We include a review of known results, mostly for a small number of sections. Comment: Typos corrected. To appear in Quarterly J. Math. (Atiyah Memorial Volume) |
