Generic properties of discrete Steklov eigenfunctions
Lixiang Chen, Bobo Hua, Yongtang Shi
Let be a finite connected graph with boundary . We prove that for a generic positive edge weight function , the Steklov eigenvalues of $(G,B,w)…
Graphs on surfaces with positive Forman curvature or corner curvature
Yohji Akama, Bobo Hua, Yanhui Su +1
On one hand, we study the class of graphs on surfaces, satisfying tessellation properties, with positive Forman curvature on each edge. Via medial graphs, we provide a new proof fo…
A curvature notion for planar graphs stable under planar duality
Yohji Akama, Bobo Hua, Yanhui Su +1
Woess \cite{Woess98} introduced a curvature notion on the set of edges of a planar graph, called -curvature in our paper, which is stable under the planar duality. We study geom…
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…
