WebThat is, for any linear scheme, the Chow groups inject into ordinary homology after tensoring with Q, and the image is exactly the smallest subspace in the weight ﬁltration. Theorem 3 is proved. ... The Chow group CHiX ⊗ Q is simply the weight BM −2i graded piece of H2i (X, Q), which gives the splitting mentioned above. In general this ...

"When the variety is smooth, the Chow groups can be interpreted as cohomology groups (compare Poincaré duality) and have a multiplication called the intersection product. The Chow groups carry rich information about an algebraic variety, and they are correspondingly hard to compute in general. See more In algebraic geometry, the Chow groups (named after Wei-Liang Chow by Claude Chevalley (1958)) of an algebraic variety over any field are algebro-geometric analogs of the homology of a topological space. … See more Projective space The Chow ring of projective space $${\displaystyle \mathbb {P} ^{n}}$$ over any field See more For a proper morphism $${\displaystyle f:X\to Y}$$ of schemes over $${\displaystyle k}$$, there is a pushforward … See more An (algebraic) vector bundle E on a smooth scheme X over a field has Chern classes ci(E) in CH (X), with the same formal properties as in topology.
