"WebLet L be a line bundle on a scheme X. 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).
