Chow ring nlab
The Chow ring is the graded ring which is the direct sum of the Chow groups, with multiplication being the intersection product. More generally one can use any adequate equivalence relation ∼ \sim (e.g. ∼ num , ∼ hom , ∼ alg \sim_{num}, \sim_{hom}, \sim_{alg} ) in place of rational equivalence, to get … See more The Chow groups of a noetherian scheme XX are the analogs of the singular homology groups of a topological space. See more Chow groups appear as the cohomology groups of motivic cohomology (see there for details) with coefficients in suitable Eilenberg-MacLane … See more Let XX be a noetherian scheme. One defines the kk-th Chow group of XX as the quotient of the group Zk(X)Z_k(X) of algebraic cycles of dimension kk by the subgroup of … See more WebOne can define the Chow ring A ∙ ( X) to be the free group generated by irreducible subvarieties, modulo rational equivalence. Multiplication comes from intersection. The …

WebApr 24, 2012 · The Chow ring of a non-singular quasi-projective algebraic variety is the ring of rational equivalence classes of algebraic cycles (cf. Algebraic cycle) on that variety. … Web2 we introduce the Chow ring with its relation to Grothendieck’s K-theory via the Grothendieck Riemann-Roch theorem. The theory of divisors on smooth projective varieties is the next best understood case and we describe its features in Section 3. A much studied case is that of zero-cycles which we discuss in Section 4.
