SUMMARY:Workshop / Seminar:Commutative Algebra Seminar: Splitting of vector bundles on toric varieties
DESCRIPTION:In 1964\, Horrocks proved that a vector bundle on a projective space splits as a sum of line bundles if and only if it has no intermediate cohomology. Generalizations of this criterion\, under additional hypotheses\, have been proven for other toric varieties\, for instance by Eisenbud-Erman-Schreyer for products of projective spaces\, by Schreyer for Segre-Veronese varieties\, and Ottaviani for Grassmannians and quadrics. This talk is about a splitting criterion for arbitrary smooth projective toric varieties\, as well as an algorithm for finding indecomposable summands of sheaves and modules in the more general setting of Mori dream spaces.
