Totally Geodesic Submanifolds of Teichmüller Space in Complex Dimension at Least Three

Longsong Jia

Let $N \subset T_{g, n}$ be a connected complex totally geodesic submanifold. We prove that if $dim_{C} N \geq 3$ , then $N$ is the image of an entire Teichmüller spac…

Characterizations of infinite circle patterns and convex polyhedra in hyperbolic 3-space

Huabin Ge, Longsong Jia, Hao Yu +1

Since Thurston pioneered the connection between circle packing (abbr. CP) and three-dimensional geometric topology, the characterization of CPs and hyperbolic polyhedra has become…

Angle structures on pseudo 3-manifolds

Huabin Ge, Longsong Jia, Faze Zhang

It is still not known whether a hyperbolic 3-manifold admits an angle structure or not. We consider angle structures with area-curvature on triangulated pseudo 3-manifolds M in thi…

Asymptotic behavior of discrete Schrödinger equations on the hexagonal triangulation

Huabin Ge, Bobo Hua, Longsong Jia +1

In this article, we prove the decay estimate for the discrete Schrödinger equation (DS) on the hexagonal triangulation. The $l^{1} \to l^{\infty}$ dispersive decay rate is $\lef…

The polyhedral decomposition of cusped hyperbolic $n$ -manifolds with totally geodesic boundary

Ge Huabin, Jia Longsong, Zhang Faze

Let $M$ be a volume finite non-compact complete hyperbolic $n$ -manifold with totally geodesic boundary. We show that there exists a polyhedral decomposition of $M$ such that each c…
