$\mathrm{SL}(3)$ Fenchel-Nielsen coordinates on the $3$-punctured sphere
Appears in collection : 2025 - T2 - WS1 - Higher rank geometric structures, Higgs bundles and physics
In this talk I'll review how the technology of spectral networks and abelianisation leads to a higher rank version of complexified Fenchel-Nielsen coordinates on the 3-punctured sphere. This is mostly based on arXiv:1906.04271.
