On the number of connected edge cover sets in a graph

Mahsa Zare, Saeid Alikhani, Mohammad Reza Oboudi

Let be a simple graph of order and size . A connected edge cover set of a graph is a subset of edges such that every vertex of the graph is incident to a…

On Gorenstein Circulant Graphs and Gorenstein SQC Graphs

Ashkan Nikseresht, Mohammad Reza Oboudi

We characterize some graphs with a Gorenstein edge ideal. In particular, we show that if is a circulant graph with vertex degree at most four or a circulant graph of the form $…

Laplacian Spectral Determination of Path-Friendship Graphs

A. Z. Abdian, A. R. Ashrafi, L. W. Beineke +1

A graph is said to be determined by the spectrum of its Laplacian matrix (DLS) if every graph with the same spectrum is isomorphic to . van Dam and Haemers (2003) conjecture…
