WebThe Chow scheme parameterizes one-dimensional cycles Z of 3 degree two on P . It is connected and has two irreducible components. One of these parameterizes conics contained in a plane and lines of multiplicity two. The other com- ponent parameterizes pairs of skew lines, singular conics and lines of multiplicity two.

For any k-dimensionsal subvariety V of X, the restriction Lj V of L to V is isomorphic to O V(C) for some Cartier divisor C on V. The Weil divisor [C] determines a well-deﬁned element in A k 1(X) which we denote by c 1(L)\V. We extend this map linearly to get the 1st Chern class c 1(L)\: A k(X) !A k 1(X). intuition painting
