由位形空间积分定义的泛等变有限型纽结不变量

A universal equivariant finite type knot invariant defined from configuration space integrals

Christine Lescop

摘要:

在上一篇文章中,我们从位形空间的等变相交构造了有理同调球面中零同调结的不变量Z。本文给出了Z的位形空间积分的一个等价定义,证明了Z在连通和下是乘法的,并证明了Z的保零拉格朗日运算公式。我们的公式推广了类似的公式,满足Kricker合理提升空Borromean手术的Kontsevich积分。它们意味着Z对于一个自然过滤是普适的。因此,根据Garoufalten和Rozansky的结果,他们认为Z等价于整同调球面上具有平凡Alexander多项式的零同调纽结的Kontsevich积分的Kricker提升.

英文摘要:

In a previous article, we constructed an invariant Z for null-homologous knots in rational homology spheres, from equivariant intersections in configuration spaces. Here we present an equivalent definition of Z in terms of configuration space integrals, we prove that Z is multiplicative under connected sum, and we prove null Lagrangian-preserving surgery formulae for Z. Our formulae generalize similar formulae that are satisfied by the Kricker rational lift of the Kontsevich integral for null Borromean surgeries. They imply that Z is universal with respect to a natural filtration. According to results of Garoufalidis and Rozansky, they therefore imply that Z is equivalent to the Kricker lift of the Kontsevich integral for null-homologous knots with trivial Alexander polynomial in integral homology spheres.
