刻划了射影平面上三个非共线点的齐次坐标环上所有有限生成分次模的Betti表锥。我们还刻画了所有有限长模的Betti表的锥形。
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.
