Recipe theorems for polynomial invariants on ribbon graphs with half-edges

Abstract

We provide recipe theorems for the Bollobàs and Riordan polynomial $\mathcal{R}$ defined on classes of ribbon graphs with half-edges introduced in arXiv:1310.3708[math.GT]. We also define a generalized transition polynomial $Q$ on this new category of ribbon graphs and establish a relationship between $Q$ and $\mathcal{R}$.
