We give a survey of graph spectral techniques used in computer sciences. The
survey consists of a description of particular topics from the theory of
graph spectra independently of the areas of Computer science in which they
are used. We have described the applications of some important graph
eigenvalues (spectral radius, algebraic connectivity, the least eigenvalue
etc.), eigenvectors (principal eigenvector, Fiedler eigenvector and other),
spectral reconstruction problems, spectra of random graphs, Hoffman
polynomial, integral graphs etc. However, for each described spectral
technique we indicate the fields in which it is used (e.g. in modelling and
searching Internet, in computer vision, pattern recognition, data mining,
multiprocessor systems, statistical databases, and in several other areas).
We present some novel mathematical results (related to clustering and the
Hoffman polynomial) as well.
