摘要

We define Fenchel-Nielsen coordinates for representations of surface groups to \(\textrm{SL}(3,{\mathbb C})\) SL ( 3 , C ) . We also show how these coordinates relate to the classical Fenchel-Nielsen coordinates and to their generalisations by Kourouniotis, Tan, Goldman, Zhang and Parker-Platis.
