WebThe problem of defining intersection products on the Chow groups of schemes has a long history. Perhaps the first example of a theorem in intersection theory is Bézout’s theorem, which tells us that two projective plane curves C and D, of degrees c and d and which have no components in common, meet in at most cd points. Furthermore if one counts the … http://sporadic.stanford.edu/reference/schemes/sage/schemes/toric/chow_group.html

The outline of the paper is as follows. In section 1, we de ne the Chow ... scheme of nite type over k.) For any variety X, let CHiX denote the group of i-dimensional algebraic cycles on X modulo rational ... 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. The Chern classes give a … See more For what follows, define a variety over a field $${\displaystyle k}$$ to be an integral scheme of finite type over $${\displaystyle k}$$.

Namely, when $${\displaystyle X}$$ is smooth over $${\displaystyle k}$$, define 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 how many cards are in soccer
