Abstract

The colored Jones polynomial associated to a knot admits an expansion of knot invariants known as the large-color expansion or Melvin-Morton-Rozansky expansion. We will show how this expansion can be derived from the universal invariant arising from a Hopf algebra D\mathbb{D}, as introduced by Bar-Natan and Van der Veen. We utilize a Mathematica implementation to compute the universal invariant ZD(K)\mathbf{Z}_{\mathbb{D}}(\mathcal{K}) up to a certain order for a given knot K\mathcal{K}, allowing for experimental verification of our theoretical results.
