Integral Cayley graphs, a notable subject within spectral graph theory, are graphs constructed from finite groups with the defining property that all eigenvalues of their associated adjacency matrices ...

Each integral circulant graph ICG(n, D) is characterised by its order n and a set D of positive divisors of n in such a way that it has vertex set ℤ/nℤ and edge set {(a, b) : a, b ∊ ℤ/nℤ, gcd(a — b, n ...
