SUMMARY:Short resolutions of the diagonal and a Horrocks-type splitting criterion in Picard rank 2
DESCRIPTION:Speaker: Mahrud Sayrafi\, University of Minnesota\n\nIn 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. Motivated by the study of indecomposable vector bundles, in 1978 Beilinson constructed a resolution of the diagonal on P^n which has been used to …
