A graph g is a mathematical structure consisting of two sets v(g) (vertices of g) and e(g) (edges of g) proper coloring of a graph is an assignment of colors either to the vertices of the graphs.

Graph structure and coloring matthieu plumettaz we denote by g= (ve) a graph with vertex set v and edge set e a graph gis claw-free if no vertex of ghas three pairwise nonadjacent neighbours claw-free graphs are a natural note that all the graphs that we consider in this thesis are 1 chapter 1 introduction nite. Graph coloring problem is to assign colors to certain elements of a graph subject to certain constraints vertex coloring is the most common graph coloring problem the problem is, given m colors, find a way of coloring the vertices of a graph such that no two adjacent vertices are colored using same color. Outline on the graph coloring problem and its generalizations thanhvu h nguyen advisor: dr thang n bui master thesis in computer science penn state harrisburg.

Acyclic coloring of graphs submitted in partial fulfillment of the requirements for the degree of master of science (by research) in computer science by for the most simple classes of graphs like complete graphs this thesis is dedicated to explore some common classes of graphs for which the acyclic chromatic. Graph coloring vertex coloring let g be a graph with no loops a k-coloring of g is an assignment of k colors to the vertices of g in such a way that adjacent vertices are assigned different colors if g has a k-coloring, then g is said to be k-coloring, then g is said to be k-colorablethe chromatic number of g, denoted by x(g), is the smallest number k for which is k-colorable. Coloring (max-rpc) problem in graphs: given a set of source-destination vertex pairs in a graph gand kcolors, nd a path connecting a source-destination pair and assign the path one of the kcolors for as many paths as possible such that the paths with the same color do. Graph coloring is a well-known and well-studied area of graph theory with many appli- cations in this thesis, we will consider two generalizations of graph coloring.

Summary the thesis deals with weighted generalizations of the classical graph vertex/edge-coloring problems motivated by scheduling arising in computer and communication.

Bachelor-thesis my bachelor thesis on graph coloring in special dags: distributed node coloring algorithms for directed graphs ad hoc wireless radio networks became more prevalent recently and will continue to grow, as mobile devices, vehicles, drones and sensors are on the rise both in the market and in research. Rectangle-free grid coloring, we are given a chessboard-like grid graph of dimensions nand m, where the vertices of the graph correspond to squares in the chessboard, and a number of allowed colors, c. Similarly, an edge coloring assigns a color to each edge so that no two adjacent edges share the same color, and a face coloring of a planar graph assigns a color to each face or region so that no two faces that share a boundary have the same color. In this thesis, we present new results on graph coloring, list coloring and packing coloring the next chapter contains a quick review of de nitions used in this thesis.

Generalized colorings of graphs honghai xu clemson university, [email protected] a graph coloring is an assignment of labels called \colors to certain elements of we study several types of such generalizations in this thesis for comprehensive surveys of graph coloring problems, we refer readers to [49,69,17. List of papers this thesis is based on the following papers, which are referred to in the text by their roman numerals i c j casselgren, coloring graphs from random lists of fixed size, manuscript.

In this thesis, we study the connections between several characteristics of graphs, including directed graphs, and hypergraphs to the spectra of related matrices for graphs, we focus on relating the minimal and maximal eigenvalues of the adjacency matrix, [mu]min and [mu]max, to graph coloring.
