WebDec 7, 2024 · Choose bases and write down explicitly the Eagon–Northcott complex for the rational normal curves of degree g = 3 and g = 4. For a 1 , ⋯ , a d ≥ 1, a rational normal scroll of type ( a 1 , a 2 , ⋯ , a d ) is defined by the 2 × 2 minors of a matrix obtained by concatenating matrices of the form ( 2.2 ) in different sets of variables: Webconstruct the tensor complex F(˚;w) from this universal tensor and a weight w2Zn+1. The following theorem illustrates how tensor complexes are a multilinear extension of the Eagon{Northcott complex and the other matrix complexes, as long as we limit the choice of w, requiring it to be a pinching weight (see De nition5.1).
