WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We define the monomial invariants of a projective variety Z; they are invariants coming from the generic initial ideal of Z. Using this notion, we generalize a result of Cook [C]: If Z is an integral variety of codimension two, satisfying the additional hypothesis sZ = sΓ, then its … Web2 ALBERTO ALZATI AND JOS´E CARLOS SIERRA Segre embedding of P1 ×Pn−1 ⊂ P2n−1 and Z ⊂ P(n2+3n)/2 is the Plu¨cker embed- ding of the Grassmannian of lines G(1,n+1), or X ⊂ P10 is a degenerate embedding of G(1,4) ⊂ P9 and Z ⊂ P15 is the minimal embedding of the 10-dimensional spinor variety S4, or X ⊂ P16 is a degenerate …
WebLetX be the base locus of a linear system L of hypersurfaces in ℙ r (ℂ). In this paper it is showed that the existence of linear syzygies for the ideal ofX has strong consequences on the fibres of the rational map associated toL. The case of hyperquadrics is particularly addressed. The results are applied to the study of rational maps and to the Perazzo’s … WebALBERTO ALZATI ∗ AND GIAN MARIO ... 2 A. ALZATI AND G. BESANA is clearly (k −1)-normal. X is said to be projectively normal if it is k-normal for all k ≥ 1. As a by-product of the proof of the above result the projective normality of a class of surfaces of degree nine in P5 which was left as an open question in [7] is established
