Topological Graph Polynomials in Colored Group Field Theory

Understand

In this paper we analyze the open Feynman graphs of the Colored Group Field Theory introduced in [arXiv:0907.2582].

• We define the boundary graph $\cG_{\partial}$ of an open graph $\cG$ and prove it is a cellular complex.
• Using this structure we generalize the topological (Bollobas-Riordan) Tutte polynomials associated to (ribbon) graphs to topological polynomials adapted to Colored Group Field Theory graphs in arbitrary dimension.
