Abstract

We generalize Bonahon-Wong's SL2(C)\mathrm{SL}_2(\mathbb{C})-quantum trace map to the setting of SL3(C)\mathrm{SL}_3(\mathbb{C}). More precisely, given a non-zero complex parameter q=e2πiq=e^{2 \pi i \hbar}, we associate to each isotopy class of framed oriented links KK in a thickened punctured surface S×(0,1)\mathfrak{S} \times (0, 1) a Laurent polynomial Trλq(K)=Trλq(K)(Xiq)\mathrm{Tr}_\lambda^q(K) = \mathrm{Tr}_\lambda^q(K)(X_i^q) in qq-deformations XiqX_i^q of the Fock-Goncharov X\mathcal{X}-coordinates for higher Teichm\"{u}ller space. This construction depends on a choice λ\lambda of ideal triangulation of the surface S\mathfrak{S}. Along the way, we propose a definition for a SLn(C)\mathrm{SL}_n(\mathbb{C})-version of this invariant.
