关于对合的代数配边环

On the algebraic cobordism ring of involutions

Olivier Haution

摘要:

我们认为协边环的对合的领域的特征不二,其元素是形式差异的类配备了一个对合的光滑投射品种,和关系产生的等变K-理论示性数。我们详细研究了这个环的结构。具体的应用提供有关品种的对合,有关的几何环境品种的固定轨迹,陈数。特别是,我们证明了代数模拟Boardman的五半定理拓扑,其中我们提供了几个概括和变化。

英文摘要:

We consider the cobordism ring of involutions of a field of characteristic not two, whose elements are formal differences of classes of smooth projective varieties equipped with an involution, and relations arise from equivariant K-theory characteristic numbers. We investigate in detail the structure of this ring. Concrete applications are provided concerning involutions of varieties, relating the geometry of the ambient variety to that of the fixed locus, in terms of Chern numbers. In particular, we prove an algebraic analog of Boardman's five halves theorem in topology, of which we provide several generalisations and variations.
