Aluffi. Let J⊂IJ⊂I be ideals in the commutative ring R. The (embedded) Aluffi algebra of I on R/JR/J is an intermediate graded algebra between the symmetric algebra and Rees Algebra of the ideal I/JI/J over R/JR/J. A pair of ideals has been dubbed an Aluffi torsion-free pair if the surjective map of the Aluffi algebra of I/JI/J onto the Rees algebra of I/JI/J is injective. In this paper we focus on the situation where J is the ideal of points in general linear position in projective space and I is its Jacobian ideal. |
