Harmonic metrics of generically regular nilpotent Higgs bundles over non-compact surfaces
Song Dai, Qiongling Li
A rank Higgs bundle is called generically regular nilpotent if but . We show that for a generically regular nilpotent Higgs bundle, if it admits…

Bounded differentials on unit disk and the associated geometry
Song Dai, Qiongling Li
For a harmonic diffeomorphism between the Poincaré disks, Wan showed the equivalence between the boundedness of the Hopf differential and the quasi-conformality. In this paper, we…

A Remark on the Rigidity of Delaunay Triangulated Plane
Song Dai
In \cite{Wu22}, under the uniformly acute condition, Wu showed the rigidity of the geodesic triangulated plane under Luo's discrete conformality. In this article, by modifying Wu's…
