Pressure metrics for cusped Hitchin components

Abstract

We study the cusped Hitchin component consisting of (conjugacy classes of) cusped Hitchin representations of a torsion-free geometrically finite Fuchsian group into PSL(d,R). We produce pressure metrics associated to the first fundamental weight and the first simple root. When $d=3$ we produce a pressure metric associated to the Hilbert length, which is new even when the Fuchsian group is cocompact.
