Bundles of rank 2 with 4 sections on curves
Seminar Room 1, Newton Institute
We study stable bundles with 4 sections on a smooth algebraic curve. We give geometric constructions for such bundles of lowest possible degree on curves of genus 10 and interpret the results in terms of generalized Clifford indices. We report on related examples and the current situations for rank 2 Brill-Noether theory.
