WebTHE INTEGRAL CHOW RING OF M 0(Pr;d), FOR dODD 3 example, the classical enumerative problem of counting the number of plane rational curves of degree dthrough 3d 1 general points was solved in [Kon95] by introducing … For example, the Chow ring of a Hirzebruch surface can be readily computed using the projective bundle formula. Recall that it is constructed as over . Then, the only non-trivial Chern class of this vector bundle is . This implies that the Chow ring is isomorphic to Remarks [ edit] 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 $${\displaystyle k}$$ is the ring See more There are several homomorphisms (known as cycle maps) from Chow groups to more computable theories. First, for a scheme X over the complex numbers, there is a … 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. The Chern classes give a close connection between vector bundles and Chow groups. Namely, let K0(X) be the See more For what follows, define a variety over a field $${\displaystyle k}$$ to be an integral scheme of finite type over $${\displaystyle k}$$. For any scheme $${\displaystyle X}$$ of … See more When the scheme $${\displaystyle X}$$ is smooth over a field $${\displaystyle k}$$, the Chow groups form a ring, not just a graded abelian … See more For a proper morphism $${\displaystyle f:X\to Y}$$ of schemes over $${\displaystyle k}$$, there is a pushforward homomorphism $${\displaystyle f_{*}:CH_{i}(X)\to CH_{i}(Y)}$$ for each integer $${\displaystyle i}$$. … See more
