A combinatorial Approach to -Ricci and Lin-Lu-Yau Ricci curvatures on Graphs
Jaewoo Jung, Young Soo Kwon, Seungjae Lee +1
In this paper, we study the -Ricci curvature and the Lin-Lu-Yau Ricci curvature on simple, connected, and locally finite graphs. For regular graphs, we introduce a combinatoria…

Generalized quaternion NCI-groups, NNN-groups and NNND-groups
Jun-Feng Yang, jia-Li Du, Yan-Quan Feng +1
A Cayley (di)graph $\Cay(G,S)$ of a finite group is called CI if, for every Cayley (di)graph $\Cay(G,T)$ of , $\Cay(G,S)\cong \Cay(G,T)$ implies that for some $Ï\i…

On the structure of Laplace characteristic polynomial for circulant foliation
Young Soo Kwon, Alexander Mednykh, Ilya Mednykh
In this paper, we describe the structure of the Laplace characteristic polynomial for the infinite family of graphs obtained as a circula…
