关于有理同调3-球面的扰动PSU(n)不变量

On Perturbative PSU(n) Invariants of Rational Homology 3-Spheres

Thang T. Q. Le

摘要:

利用量子PSU(n)-不变量构造了有理同调3-球面的幂级数不变量.该幂级数可以看作是微扰不变量,对应于假设的Witten积分中平凡联系的贡献。这概括了一个结果Ohtsuki(的$n=2$情况下),使他的定义有限型不变量的3流形。该证明利用了来自仿射李代数理论和Kontsevich积分理论的量子不变量(链接)的一些对称性。

英文摘要:

We construct power series invariants of rational homology 3-spheres from quantum PSU(n)-invariants. The power series can be regarded as perturbative invariants corresponding to the contribution of the trivial connection in the hypothetical Witten's integral. This generalizes a result of Ohtsuki (the $n=2$ case) which led him to the definition of finite type invariants of 3-manifolds. The proof utilizes some symmetry properties of quantum invariants (of links) derived from the theory of affine Lie algebras and the theory of the Kontsevich integral.
