Tate Resolutions for Segre Embeddings

David Cox, Evgeny Materov

Published 2007-11-04, updated 2008-06-07Version 3

We give an explicit description of the terms and differentials of the Tate resolution of sheaves arising from Segre embeddings of $\P^a\times\P^b$. 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.
