The Packing Chromatic Number of Random d-regular Graphs [PDF]
Let G = (V (G),E(G)) be a simple graph of order n and let i be a positive integer. Xi superset V (G) is called an i-packing if vertices in Xi are pairwise distance more than i apart. A packing coloring of G is a partition X = {X1,X2,X3, . . .

On the Packing Chromatic Number on Hamming Graphs and General Graphs
The packing chromatic number $χ_ρ(G)$ of a graph $G$ is the smallest integer $k$ needed to proper color the vertices of $G$ in such a way the distance between any two vertices having color $i$ be at least $i+1$. We obtain $χ_ρ(H_{q,m})$ for $m=3$, where $H_{q,m}$ is the Hamming graph of words of length $m$ and alphabet with $q$ symbols, and tabulate ...

Packing Chromatic Number of Cycle Related Graphs
The packing chromatic number I‡ (G) of a graph G is the smallest integer k for which there exists a mapping I : V (G) −→ {1, 2, ..., k} such that any two vertices of color i are at distance at least i + 1. It is a frequency assignment problem used in wireless networks, which is also called Broadcasting coloring.

Packing chromatic numbers of finite super subdivisions of graphs
Given a graph G and a positive integer i, an i-packing in G is a subset W of the vertex set of G such that the distance between any two distinct vertices from W is greater than i. The packing chromatic number of a graph G, ??(G), is the smallest integer k such that the vertex set of G can be partitioned into sets Vi, i ?

Computer search for packing chromatic number for different lattices [PDF]
Pojem pakirnega kromatskega števila prihaja iz področja načrtovanja frekvenc v brezžičnih omrežjih. Pri pakiranju k-barv grafa G, morajo biti vozlišča grafa z barvo i paroma na večji razdalji kot si.

Algebraic Properties of Chromatic Polynomials and Their Roots [PDF]
In this thesis we examine chromatic polynomials from the viewpoint of algebraic number theory. We relate algebraic properties of chromatic polynomials of graphs to structural properties of those graphs for some simple families of graphs.

The s-packing chromatic number of a graph [PDF]
Let S = (a₁, a₂, ...) be an infinite nondecreasing sequence of positive integers. An S-packing k-coloring of a graph G is a mapping from V(G) to {1,2,...,k} such that vertices with color i have pairwise distance greater than $a_i$, and the S-packing ...
