Distance Powers and Distance Matrices of Integral Cayley Graphs over Abelian Groups
W. Klotz, T. Sander
It is shown that distance powers of an integral Cayley graph over an abelian group are again integral Cayley graphs over that group. Moreover, it is proved that distance matrices o…

The maximal energy of classes of integral circulant graphs
Jürgen W. Sander, Torsten Sander
The energy of a graph is the sum of the moduli of the eigenvalues of its adjacency matrix. We study the energy of integral circulant graphs, also called gcd graphs, which can be ch…
