The Chow Group Real Estate Huntington Beach CA
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. The elements of the Chow group are formed out of subvarieties (so-called algebraic cycles) in a … 查看更多內容 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 finite type over $${\displaystyle k}$$, an algebraic … 查看更多內容 Projective space The Chow ring of projective space $${\displaystyle \mathbb {P} ^{n}}$$ over any field 查看更多內容 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 … 查看更多內容 Some of the deepest conjectures in algebraic geometry and number theory are attempts to understand Chow groups. For example: • 查看更多內容 When the scheme $${\displaystyle X}$$ is smooth over a field $${\displaystyle k}$$, the Chow groups form a ring, not just a graded abelian group. Namely, when $${\displaystyle X}$$ is smooth over $${\displaystyle k}$$, define 查看更多內容 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 $${\displaystyle i}$$. For example, for a 查看更多內容 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.
