Chow group of scheme
WebIn general, the Chow group is an algebraic version of a homology theory. That is, the objects are formal linear combinations of submanifolds modulo relations. In particular, the objects of the Chow group are formal linear combinations of algebraic subvarieties and the equivalence relation is rational equivalence.

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). crayford clubWebgroup of Dperf(X) as the Grothendieck group of the p-th subquotient of the filtration.
