Infinitesimal Rigidity of Cyclic Surfaces and Alternating Surfaces

Qiongling Li, Junming Zhang

We study the infinitesimal rigidity of equivariant minimal maps from the universal cover of a smooth oriented surface (possibly non-compact) into a Riemannian symmetric space, focu…

Compact relative $SO_{0} (2, q)$ -character varieties of punctured spheres

Yu Feng, Junming Zhang

We prove that there are relative $SO_{0} (2, q)$ -character varieties of the punctured sphere which are compact, totally non-hyperbolic and contain a dense representation. This…

Non-maximal Anosov representations from surface groups to $SO_{0} (2, 3)$

Junming Zhang

We prove the representation given by a stable $I^\pm_{1}$ -cyclic parabolic $SO_{0} (2, 3)$ -Higgs bundle through the non-Abelian Hodge correspondence is ${I^\pm_{2}}$ -almost dominated.…
