On the size of outerplanar graphs with positive Lin-Lu-Yau Ricci curvature
Xiaonan Liu, Linyuan Lu, Zhiyu Wang
In this paper, extending a result of Brooks et.al. [arXiv:2403.04110], we show that if an outerplanar graph with minimum degree at least has positive Lin-Lu-Yau curvature o…
Ricci Curvature Formula: Applications to Bonnet-Myers Sharp Irregular Graphs
Yupei Li, Linyuan Lu
In this paper, we establish a simple formula for computing the Lin-Lu-Yau Ricci curvature on graphs. For any edge in a simple locally finite graph , the curvature …
Maximum spectral gaps of graphs
George Brooks, William Linz, Linyuan Lu
The spread of a graph is the difference between the largest and smallest eigenvalues of its adjacency matrix. Breen, Riasanovsky, Tait and Urschel recently determin…
Maximum spread of -minor-free graphs
William Linz, Linyuan Lu, Zhiyu Wang
The spread of a graph is the difference between the largest and smallest eigenvalue of the adjacency matrix of . In this paper, we consider the family of graphs which contai…
