Integral graphs and (k, τ)-regular sets
A subset of the vertex set of a graph G, W ⊆ V (G), is a (k, τ)-regular set if it induces a k-regular subgraph of G and every vertex not in the subset has τ neighbors in it. In this paper we deal with the existence of (k, τ)-regular sets associated with all distinct eigenvalues. We show some familie...
