Cacti with maximum Kirchhoff index

Wen-Rui Wang, Xiang-Feng Pan

The concept of resistance distance was first proposed by Klein and Randić. The Kirchhoff index $K f (G)$ of a graph $G$ is the sum of resistance distance between all pairs of vertice…

Further results regarding the degree resistance distance of cacti

Jia-Bao Liu, Wen-Rui Wang, Yong-Ming Zhang +1

A graph $G$ is called a cactus if each block of $G$ is either an edge or a cycle. Denote by $C a c t (n; t)$ the set of connected cacti possessing $n$ vertices and $t$ cycles. In this p…
