Energy, Laplacian energy of double graphs and new families of equienergetic graphs

S. Pirzada, Hilal A Ganie

For a graph $G$ with vertex set $V (G) = {v_{1}, v_{2}, \dots, v_{n}}$ , the extended double cover $G^{*}$ is a bipartite graph with bipartition (X, Y), $X = {x_{1}, x_{2}, \dots, x_{n}}$ and $Y…

Imbalances in directed multigraphs

S. Pirzada, T. A. Naikoo, U. Samee +1

In a directed multigraph, the imbalance of a vertex $v_{i}$ is defined as $b_{v_{i}} = d_{v_{i}}^{+} - d_{v_{i}}^{-}$ , where $d_{v_{i}}^{+}$ and $d_{v_{i}}^{-}$ denote the outdegree an…

Score lists in multipartite hypertournaments

Shariefuddin Pirzada, Guofei Zhou, Antal Iványi

Given non-negative integers $n_{i}$ and $α_{i}$ with $0 \leq α_{i} \leq n_{i}$ $(i = 1, 2, ..., k)$ , an $[α_{1}, α_{2}, ..., α_{k}]$ - $k$ -partite hypertournament on $\sum_{1}^{k} n_{i}$ vertic…
