Ricci curvature on birth-death processes
Bobo Hua, Florentin Münch
In this paper, we study curvature dimension conditions on birth-death processes which correspond to linear graphs, i.e., weighted graphs supported on the infinite line or the half…
Payne-Polya-Weinberger, Hile-Protter and Yang's inequalities for Dirichlet Laplace eigenvalues on integer lattices
Bobo Hua, Yong Lin, Yanhui Su
In this paper, we prove some analogues of Payne-Polya-Weinberger, Hile-Protter and Yang's inequalities for Dirichlet (discrete) Laplace eigenvalues on any subset in the integer lat…
The first gap for total curvatures of planar graphs with nonnegative curvature
Bobo Hua, Yanhui Su
We prove that the total curvature of a planar graph with nonnegative combinatorial curvature is at least if it is positive. Moreover, we classify the metric structur…
Riesz transforms for bounded Laplacians on graphs
Li Chen, Thierry Coulhon, Bobo Hua
We study several problems related to the boundedness of Riesz transforms for graphs endowed with so-called bounded Laplacians. Introducing a proper notion of gradient of f…
First eigenvalue estimates of Dirichlet-to-Neumann operators on graphs
Bobo Hua, Yan Huang, Zuoqin Wang
Following Escobar [Esc97] and Jammes [Jam15], we introduce two types of isoperimetric constants and give lower bound estimates for the first nontrivial eigenvalues of Dirichlet-to-…
Davies-Gaffney-Grigor'yan lemma on simplicial complexes
Bobo Hua, Xin Luo
We prove Davies-Gaffney-Grigor'yan lemma for heat kernels of bounded discrete Hodge Laplacians on simplicial complexes.
