A Diagrammatic method for an invariant related to the Chern-Simons perturbation theory

Abstract

The defect $d(M,\rho )$ is an invariant of a compact oriented 3-manifold $M$ with a representation $\rho$ of the fundamental group. In this article we give a diagrammatic method for $d$ of knot exteriors by using knot diagrams.
