Bundles of rank 2 with 4 sections on curves

Tuesday 14th June 2011 - 11:30 to 12:30
INI Seminar Room 1
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.
