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 ...

One of the ways that Pi Mu Epsilon promotes scholarship in mathematics is through the publishing of the Pi Mu Epsilon Journal. The sole purpose of this journal is to present papers and mathematical ...

Let G be a non-trivial finite group, S ⊆ G \ {e} be a set such that if a ϵ S, then a⁻¹ ϵ S and e be the identity element of G. Suppose that Cay(G, S) is the Cayley graph with the vertex set G such ...
