我们提出了陈-西蒙斯规范场理论的微扰理论,并证明了它确实给二阶纽结不变量。我们确定这些不变量,并表明,事实上,我们得到了一个以前未知的积分公式的Arf不变的结,在完全符合早期的非微扰结果的维滕。我们概述了我们的期望的行为的理论超过两个循环。
We present the perturbation theory of the Chern-Simons gauge field theory and prove that to second order it indeed gives knot invariants. We identify these invariants and show that in fact we get a previously unknown integral formula for the Arf invariant of a knot, in complete agreement with earlier non-perturbative results of Witten. We outline our expectations for the behavior of the theory beyond two loops.
