一个二阶代数纽结和谐群

A Second Order Algebraic Knot Concordance Group

Mark Powell

摘要:

我们定义了一个代数群,包括对称的链复形,它捕获的前两个阶段的Cochran-Orr-Teichner可解过滤的结和谐组在一个单一的障碍。为了实现这一点,我们在每个链复形上施加额外的结构,这对基本群进行了额外的控制,特别是对它们可以一致地改变的方式进行了控制。

英文摘要:

We define an algebraic group comprising symmetric chain complexes which captures the first two stages of the Cochran-Orr-Teichner solvable filtration of the knot concordance group in a single obstruction. To achieve this we impose additional structure on each chain complex which puts extra control on the fundamental groups, and in particular on the way in which they can change in a concordance.
