Limits of cubic differentials and buildings

J Loftin, A Tamburelli, M Wolf - arXiv preprint arXiv:2208.07532, 2022 - arxiv.org
In the Labourie-Loftin parametrization of the Hitchin component of surface group
representations into SL (3, R), we prove an asymptotic formula for holonomy along rays in …

Arc coordinates for maximal representations

M Magnani - arXiv preprint arXiv:2405.10065, 2024 - arxiv.org
We generalize arc coordinates for maximal representations from a hyperbolic surface with
boundary into $\text {PSp}(4,\mathbb {R}) $, focusing on the case where the surface is a pair …

A closed ball compactification of a maximal component via cores of trees

We show that, in the character variety of surface group representations into the Lie group
$\mathrm {PSL}(2,\mathbb {R})\times\mathrm {PSL}(2,\mathbb {R}) $, the compactification of …

On Hitchin's equations for cyclic G-Higgs bundles

N Sagman, O Tošić - arXiv preprint arXiv:2410.20853, 2024 - arxiv.org
We develop a Lie-theoretic perspective on Hitchin's equations for cyclic $ G $-Higgs
bundles, which we use to study analytic and geometric properties of harmonic maps. Among …

High-energy harmonic maps and degeneration of minimal surfaces

C Ouyang - Geometry & Topology, 2023 - msp.org
Let S be a closed surface of genus g≥ 2 and ρ a maximal PSL⁡(2, ℝ)× PSL⁡(2, ℝ) surface
group representation. By a result of Schoen, there is a unique ρ–equivariant minimal surface …

We show that, in the character variety of surface group representations into the Lie group
PSL⁡(2, ℝ)× PSL⁡(2, ℝ), the compactification of the maximal component introduced by the …

Degeneration of minimal surfaces in the bidisc

C Ouyang - 2020 - search.proquest.com
This thesis studies the degeneration of a particular class of minimal surfaces in the bidisc,
describing both the limiting metric structure and geometry. Minimal surfaces inside …
