对于特征为零的域上的任意簇,我们关联一个复杂的Chow动机,它在同伦上是唯一有界的。我们推断,任何品种有一个自然的欧拉特征的Grothendieck群的周动机。证明了复数上任意奇异簇的整系数上同调都有一个自然的权滤子。我们定义代数K理论与“紧支持”。
To an arbitrary variety over a field of characteristic zero, we associate a complex of Chow motives, which is, up to homotopy, unique and bounded. We deduce that any variety has a natural Euler characteristic in the Grothendieck group of Chow motives. We show that the cohomology with integer coefficients of any singular variety over the complex numbers has a natural weight filtration. We define algebraic K-theory with "compact supports".
