The line graph of the crown graph is distance integral

S. Morteza Mirafzal

The distance eigenvalues of a connected graph $G$ are the eigenvalues of its distance matrix $D (G)$ . A graph is called distance integral if all of its distance eigenvalues are inte…

A class of integral graphs constructed from the hypercube

S. Morteza Mirafzal

In this paper, we determine the set of all distinct eigenvalues of the line graph which is induced by the first and second layers of the hypercube $Q_{n}$ , $n > 3$ . We show that this…

A note on the automorphism groups of Johnson graphs

S. Morteza Mirafzal

The Johnson graph $J (n, i)$ is defined as the graph whose vertex set is the set of all $i$ -element subsets of ${1, ..., n}$ , and two vertices are adjacent whenever the cardina…
