Tate resolutions for Segre embeddings

David A. Cox and Evgeny Materov

Vol. 2 (2008), No. 5, 523–549
Abstract

We give an explicit description of the terms and differentials of the Tate resolution of sheaves arising from Segre embeddings of a × b. We prove that the maps in this Tate resolution are either coming from Sylvester-type maps, or from Bezout-type maps arising from the so-called toric Jacobian.

Keywords
