and \documentclass{article} \usepackage{amsmath,amsfonts,amssymb}\pagestyle{empty}\begin{document} \end{document}, the distance graph P has vertex set {0,1,…,n − 1} and edge set {ij | 0 ≤ i,j ≤ n − 1,|j − i| ∈ D}. The class of distance graphs generalizes...
For n∈N and D⊆N, the distance graph PnD has vertex set {0,1,…,n−1} and edge set {ij∣0≤i,j≤n−1,|j−i|∈D}. Note that the important and very well-studied circulant graphs coincide with the regular distance graphs.A fundamental result concerning circulant graphs is that for these graphs, a simple greatest common divisor condition, their connectivity, and the existence of a Hamiltonian cycle are all equivalent...
