The cone of Betti tables over three non-collinear points in the plane

arXiv:1501.00207 · doi:10.1216/JCA-2016-8-4-537

Abstract

We describe the cone of Betti tables of all finitely generated graded modules over the homogeneous coordinate ring of three non-collinear points in the projective plane. We also describe the cone of Betti tables of all finite length modules.
