簇上丛的代数配边性

Algebraic cobordism of bundles on varieties

Y. -P. Lee, R. Pandharipande

摘要:

二重点关系定义了簇上丛的代数配边的自然理论。我们构造了Spec(C)上相应的簇和秩的所有维数的配边群的一个简单基(在有理数上).基由射影空间的乘积上的分裂丛组成。证明了簇上丛的完全理论是标准代数配边标量理论的推广。

英文摘要:

The double point relation defines a natural theory of algebraic cobordism for bundles on varieties. We construct a simple basis (over the rationals) of the corresponding cobordism groups over Spec(C) for all dimensions of varieties and ranks of bundles. The basis consists of split bundles over products of projective spaces. Moreover, we prove the full theory for bundles on varieties is an extension of scalars of standard algebraic cobordism.
