This book gives an elementary treatment of the basic material about
graph spectra, both for ordinary, and Laplace and Seidel spectra. The
text progresses systematically, by covering standard topics before
presenting some new material on trees, strongly regular graphs,
two-graphs, association schemes, p-ranks of configurations and similar
topics. Exercises at the end of each chapter provide practice and vary
from easy yet interesting applications of the treated theory, to little
excursions into related topics. Tables, references at the end of the
book, an author and subject index enrich the text.
Spectra of Graphs is written for researchers, teachers and graduate
students interested in graph spectra. The reader is assumed to be
familiar with basic linear algebra and eigenvalues, although some more
advanced topics in linear algebra, like the Perron-Frobenius theorem and
eigenvalue interlacing are included.
