A discrete uniformization theorem for decorated piecewise hyperbolic metrics on surfaces
Xu Xu, Chao Zheng
In this paper, we study a natural discretization of the smooth Gaussian curvature on surfaces. A discrete uniformization theorem is established for this discrete Gaussian curvature…
Rigidity of generalized Thurston's sphere packings on 3-dimensional manifolds with boundary
Xu Xu, Chao Zheng
Motivated by Guo-Luo's generalized circle packings on surfaces with boundary \cite{GL2}, we introduce the generalized Thurston's sphere packings on 3-dimensional manifolds with bou…
Rigidity and deformation of generalized sphere packings on 3-dimensional manifolds with boundary
Xu Xu, Chao Zheng
Motivated by Guo-Luo's generalized circle packings on surfaces with boundary \cite{GL2}, we introduce the generalized sphere packings on 3-dimensional manifolds with boundary. Then…
Combinatorial curvature flows with surgery for inversive distance circle packings on surfaces
Xu Xu, Chao Zheng
Inversive distance circle packings introduced by Bowers-Stephenson are natural generalizations of Thurston's circle packings on surfaces. To find piecewise Euclidean metrics on sur…
Absolute continuity of the integrated density of states in the localized regime
Jing Wang, Xu Xu, Jiangong You +1
We establish the absolute continuity of the integrated density of states (IDS) for quasi-periodic Schrödinger operators with a large trigonometric potential and Diophantine frequen…
Beam Search for Learning a Deep Convolutional Neural Network of 3D Shapes
Xu Xu, Sinisa Todorovic
This paper addresses 3D shape recognition. Recent work typically represents a 3D shape as a set of binary variables corresponding to 3D voxels of a uniform 3D grid centered on the…
