Projective space The Chow ring of projective space $${\displaystyle \mathbb {P} ^{n}}$$ over any field $${\displaystyle k}$$ is the ring $${\displaystyle CH^{*}(\mathbb {P} ^{n})\cong \mathbf {Z} [H]/(H^{n+1}),}$$ where $${\displaystyle H}$$ is the class of a hyperplane (the zero locus of a single linear function). … 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 For a proper morphism $${\displaystyle f:X\to Y}$$ of schemes over $${\displaystyle k}$$, there is a pushforward … 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 homomorphism from Chow groups to Borel–Moore homology: See more Some of the deepest conjectures in algebraic geometry and number theory are attempts to understand Chow groups. For example: • The Mordell–Weil theorem implies that the divisor class group CHn-1(X) is finitely generated for any … 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 group. Namely, when $${\displaystyle X}$$ is … 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 WebThe (almost) integral Chow ring of Mf7 3 Michele Pernice Abstract This paper is the third in a series of four papers aiming to describe the (almost integral) Chow ring of M 3, the moduli stack of stable curves of genus 3.
