Graphs with nonnegative curvature outside a finite subset, harmonic functions and number of ends
Bobo Hua, Florentin Münch
We study graphs with nonnegative Bakry-Émery curvature or Ollivier curvature outside a finite subset. For such a graph, via introducing the discrete Gromov-Hausdorff convergence we…
Every Salami has two ends
Bobo Hua, Florentin Münch
A salami is a connected, locally finite, weighted graph with non-negative Ollivier Ricci curvature and at least two ends of infinite volume. We show that every salami has exactly t…
Combinatorial Ricci flows with applications to the hyperbolization of cusped 3-manifolds
Ke Feng, Huabin Ge, Bobo Hua
In this paper, we adopt combinatorial Ricci curvature flow methods to study the existence of cusped hyperbolic structure on 3-manifolds with torus boundary. For general pseudo 3-ma…
Universal inequalities for Dirichlet eigenvalues on discrete groups
Bobo Hua, Ariel Yadin
We prove universal inequalities for Laplacian eigenvalues with Dirichlet boundary conditions on subsets of certain discrete groups. The study of universal inequalities on Riemannia…
Time analyticity of ancient solutions to the heat equation on graphs
Fengwen Han, Bobo Hua, Lili Wang
We study the time analyticity of ancient solutions to heat equations on graphs. Analogous to Dong and Zhang [DZ19], we prove the time analyticity of ancient solutions on graphs und…
Ancient caloric functions on graphs with unbounded Laplacians
Bobo Hua
We study ancient solutions of polynomial growth to both continuous-time and discrete-time heat equations on graphs with unbounded Laplacians. We generalize Colding and Minicozzi's…
