The purpose of this volume is to review the results in spectral graph theory which have appeared since 1978. The problem of characterizing graphs with least eig
This introductory text explores the theory of graph spectra: a topic with applications across a wide range of subjects, including computer science, quantum chem
The theory of graph spectra can, in a way, be considered as an attempt to utilize linear algebra including, in particular, the well-developed theory of matrices
