Vector Bundles on a Neighborhood of an Exceptional Curve and Elementary Transformations
Edoardo Ballico, Elizabeth Gasparim
Let W be the germ of a smooth complex surface around an exceptional curve and let E be a rank 2 vector bundle on W. We study the cohomological properties of a finite sequence $E_i,…
