Exact Distance Graphs of Product Graphs [PDF]
Given a graph $G$, the exact distance-$p$ graph $G^{[\natural p]}$ has $V(G)$ as its vertex set, and two vertices are adjacent whenever the distance between them in $G$ equals $p$. We present formulas describing the structure of exact distance-$p$ graphs of the Cartesian, the strong, and the lexicographic product.

On the graph of large distances [PDF]
Let \(S\) be a set of \(n\) points in the plane and let \(d_1>d_2>..\). be the different distances determined by the set \(S\). The graph \(G(S,k)\) is considered whose vertex set is S and in which two vertices are adjacent if and only if their distance is at least \(k\). The chromatic number \(\chi(G(S,k))\) of \(G(S,k)\) is studied. It is proved that

On the Change of Distance Energy of Complete Bipartite Graph due to Edge Deletion
The distance energy of a graph is defined as the sum of absolute values of distance eigenvalues of the graph. The distance energy of a graph plays an important role in many fields.

Coloring Some Finite Sets in ℝn
This note relates to bounds on the chromatic number χ(ℝn) of the Euclidean space, which is the minimum number of colors needed to color all the points in ℝn so that any two points at the distance 1 receive different colors. In [6] a sequence of graphs Gn

The distance seidel spectrum of some graph operations [PDF]
The distance matrix, distance eigenvalue, and distance energy of a connected graph have been studied in detail in literature where as the study on distance seidel matrix associated with a connected graph is in progress. The eigenvalues ∂1S≥∂2S≥ ...

A Characterization of Maximal Outerplanar-Open Distance Pattern Uniform Graphs
Let A ⊆ V(H) of any graph H, every node w of H be labeled using a set of numbers; , where d(w,v) denotes the distance between node w and the node v in H, known as its open A-distance pattern. A graph H is known as the open distance-pattern uniform (odpu)
