Abstract
The expectation value of Wilson loop operators in three-dimensional Chern-Simons gauge theory gives a known knot invariant: the Kauffman polynomial. Here this result is derived, at the first order, via a simple variational method. With the same procedure the skein relation for Sp(N) are also obtained. Jones polynomial arises as special cases: Sp(2), , and . These results are confirmed and extended up to the second order, by means of perturbation theory, which moreover let us establish a duality relation between and invariants. A correspondence between the first orders in perturbation theory of , Sp(2) or SU(2) Chern-Simons quantum holonomy’s traces and the partition function of the Potts model is built.
