Fenchel-Nielsen Coordinates for Maximal Representations
Tobias Strubel
We develop Fenchel-Nielsen coordinates for representations of surface groups into Sp(2n,R) with maximal Toledo invariant. Analogous to classical Fenchel-Nielsen coordinates on the…

Cross ratios, translation lengths and maximal representations
Tobias Hartnick, Tobias Strubel
We define a family of four-point invariants for Shilov boundaries of bounded symmetric domains of tube type, which generalizes the classical four-point cross ratio on the unit circ…
