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 ...

In 2014, Wang et al. presented in the necessary and sufficient conditions for a complete multipartite graph to be a Seidel integral graph, and also constructed some Seidel integral graphs. Berman et ...

We present a simple graph integral equivalent to a multiple of the circuit partition polynomial. Let G be a directed graph, and let k be a positive integer. Associate with each vertex v of G an ...
