Syzygy algebras for Segre embeddings

  • I. V. Netay
Article

Abstract

We describe the syzygy spaces for the Segre embedding ℙ(U) × ℙ(V) ⊂ ℙ(UV) in terms of representations of GL(U) × GL(V) and construct the minimal resolutions of the sheaves
(a, b) in D(ℙ(UV)) for a ⩽ −dim(U) and b ⩽ −dim(V). We also prove a property of multiplication in syzygy spaces of the Segre embedding.

Key words

syzygy algebra Koszul cohomology representations of GL Segre embedding derived category of coherent sheaves
