Abstract

Exceptional vector bundles are a special class of rigid vector bundles. In particular, the moduli space of exceptional bundles with a fixed Chern character is discrete. On P^3, it has been conjectured that such moduli space consists of a single point. In this talk, we prove this conjecture.
