Abstract

Garoufalidis, Thurston and Zickert parametrized boundary-unipotent representations of a 3–manifold group into SL(n, ) using Ptolemy coordinates, which were inspired by A–coordinates on higher Teichmüller space due to Fock and Goncharov. We parametrize representations into PGL(n, ) using shape coordinates, which are a 3–dimensional analogue of Fock and Goncharov’s X–coordinates. These coordinates satisfy equations generalizing Thurston’s gluing equations. These equations are of Neumann–Zagier type and satisfy symplectic relations with applications in quantum topology. We also explore a duality between the Ptolemy coordinates and the shape coordinates.
