The weighted Forman and Lin-Lu-Yau Ricci flow on graphs
Shuliang Bai, Shuang Liu, Xin Lai
In this paper, we propose a type of Ricci flow on graphs where the probability distribution for the Lin-Lu-Yau curvature remains constant over time, and also study the related Form…

Ricci Flow on Weighted Digraphs with Balancing Factor
Shuliang Bai, Rui Li, Shuang Liu +1
Ricci curvature and Ricci flow have proven to be powerful tools for analyzing the geometry of discrete structures, particularly on undirected graphs, where they have been applied t…

On the Ricci flow on Trees
Shuliang Bai, Bobo Hua, Yong Lin +1
In this paper, we study the evolution of metrics on finite trees under continuous-time Ricci flows based on the Lin-Lu-Yau version of Ollivier Ricci curvature. We analyze long-time…
