	Graph theory - Wikipedia, the free encyclopedia
		Informally, a graph is a set of objects called vertices (or nodes) connected by links called edges (or arcs) which can be directed (assigned a direction).
		Graphs are represented graphically by drawing a dot for every vertex, and drawing an arc between two vertices if they are connected by an edge.
		A graph drawing should not be confused with the graph itself (the abstract, non-graphical structure) as there are several ways to structure the graph drawing.

	Algebraic graph theory - Wikipedia, the free encyclopedia
		Algebraic graph theory is a branch of mathematics.
		In one sense, algebraic graph theory studies graphs in connection with linear algebra.
		This part of algebraic graph theory is also called the spectral graph theory.

		This book is primarily aimed at graduate students and researchers in graph theory, combinatorics, or discrete mathematics in general.
		However, all the necessary graph theory is developed from scratch, so the only pre-requisite for reading it is a first course in linear algebra and a small amount of elementary group theory.
		--It is sketchy on chromatic polynomial, planar graph.

		Other results include the assertion that a connected graph with least eigenvalue -2 is exceptional if and only if it has an exceptional star complement for the eigenvalue -2, and a description of the eigenspace for -2 in generalized line graphs.
		Most graphs that are known to be DS are either small, so that the property can be proved by complete enumeration, or they have a high degree of regularity.
		Several graph invariants based on the spectra of matrices associated with the graph, with the property that they are minor monotone, will be presented and compared.

		The time has now come when graph theory should be part of the education of every serious student of mathematics and computer science, both for its own sake and to enhance the appreciation of mathematics as a whole.
		This book is an in-depth account of graph theory, written with such a student in mind; it reflects the current state of the subject and emphasizes connections with other branches of pure mathematics.
		Recognizing that graph theory is one of several courses competing for the attention of a student, the book contains extensive descriptive passages designed to convey the flavor of the subject and to arouse interest.

	Spectral Graph Theory (Site not responding. Last check: 2007-11-05)
		The underlying graph itself is introduced in a natural way by a move set (mutation operator, search strategy) on the set of possible configurations or genes.
		The correlation functions are in turn uniquely determined by the geometry of the underlying configuration space and the nearest neighbor correlation of the elementary landscape.
		We conclude that the algebraic approach to fitness landscape analysis can be extended to recombination spaces and provides an effective way to analyze the relative hardness of a landscape for a given recombination operator.

		on two generators a and b In mathematics, a Cayley graph, named after Arthur Cayley, is a graph theory that encodes the structure of a group (mathematics).
		It is a central tool in combinatorial group theory and geometric group theory.
		Insights into the structure of the group can be obtained by studying the adjacency matrix of the graph and in particular applying the theorems of spectral graph theory.
