Laplacian Coefficients of a Forest in terms of the Number of Closed Walks in the Forest and its Line Graph
Ali Ghalavand, Ali Reza Ashrafi
Let be a finite simple graph with Laplacian polynomial . In an earlier paper, the coefficients and for tree with respec…
On a Conjecture about Degree Deviation Measure of Graphs
Ali Ghalavand, Ali Reza Ashrafi
Let G be an n-vertex graph with m edges. The degree deviation measure of G is defined as s(G)=sum v in V(G)|degG(v)-(2m/n)|, where n and m are the number of vertices and edges of G…
No two Jellyfish graphs are L-cospectral and Q-cospectral
A. Z. Abdian, A. R. Ashrafi
In this paper, it is proved that the jellyfish graphs, a natural generalization of sun graphs, are both DLS and DQS.
First and Second Maximum of Randić Index Among all Cyclic Graphs of a Given Order
Ali Reza Ashrafi, Ali Ghalavand, Marzieh Pourbabaee
Suppose is a simple graph with edge set . The Randić index is defined as , where denotes th…
Graphs determined by signless Laplacian spectra
Ali Zeydi Abdian, Afshin Behmaram, Gholam Hossein Fath-Tabar
In the past decades, graphs that are determined by their spectrum have received more attention, since they have been applied to several fields, such as randomized algorithms, combi…
Vertex and edge orbits of Fibonacci and Lucas cubes
Ali Reza Ashrafi, Jernej Azarija, Khadijeh Fathalikhani +2
The Fibonacci cube is obtained from the -cube by removing all the vertices that contain two consecutive 1s. If, in addition, the vertices that start and end with 1 a…
