Uniform non-homogeneous vector bundles: A counterexample to the conjecture of Drézet and Ballico-Ellia
Abstract
We construct a rank-9 uniform non-homogeneous vector bundle on ℙ5. This yields the first counterexample to the longstanding open conjecture that every uniform vector bundle of rank r<2n on ℙn is homogeneous.
