实algebraic varieties II的权过滤:经典同调

The weight filtration for real algebraic varieties II: Classical homology

Clint McCrory, Adam Parusinski

摘要:

我们关联到每个真正的代数品种过滤链复形,重量复杂,这是定义良好的过滤准同构,并诱导经典(composite支持)的同源性与Z/2系数模拟的重量过滤复杂的代数品种。这补充了我们以前对Borel-Moore同调的权重过滤的定义。

英文摘要:

We associate to each real algebraic variety a filtered chain complex, the weight complex, which is well-defined up to filtered quasi-isomorphism, and which induces on classical (compactly supported) homology with Z/2 coefficients an analog of the weight filtration for complex algebraic varieties. This complements our previous definition of the weight filtration of Borel-Moore homology.
