Wiener index of graphs with fixed number of pendant or cut vertices

Dinesh Pandey, Kamal Lochan Patra

The Wiener index of a connected graph is defined as the sum of the distances between all unordered pair of its vertices. In this paper, we characterize the graphs which extremize t…

On the minimum degree of the power graph of a finite cyclic group

Ramesh Prasad Panda, Kamal Lochan Patra, Binod Kumar Sahoo

The power graph $P (G)$ of a finite group $G$ is the simple undirected graph whose vertex set is $G$ , in which two distinct vertices are adjacent if one of them is an inte…

Laplacian eigenvalues of the zero divisor graph of the ring $Z_{n}$

Sriparna Chattopadhyay, Kamal Lochan Patra, Binod Kumar Sahoo

We study the Laplacian eigenvalues of the zero divisor graph $Γ (Z_{n})$ of the ring $Z_{n}$ and prove that $Γ (Z_{p^{t}})$ is Laplacia…
