A Polynomial Approach to Linear Algebra is a text which is heavily
biased towards functional methods. In using the shift operator as a
central object, it makes linear algebra a perfect introduction to other
areas of mathematics, operator theory in particular. This technique is
very powerful as becomes clear from the analysis of canonical forms
(Frobenius, Jordan). It should be emphasized that these functional
methods are not only of great theoretical interest, but lead to
computational algorithms. Quadratic forms are treated from the same
perspective, with emphasis on the important examples of Bezoutian and
Hankel forms. These topics are of great importance in applied areas such
as signal processing, numerical linear algebra, and control theory.
Stability theory and system theoretic concepts, up to realization
theory, are treated as an integral part of linear algebra.
This new edition has been updated throughout, in particular new sections
have been added on rational interpolation, interpolation using H^{\nfty}
functions, and tensor products of models.
Review from first edition:
"...the approach pursed by the author is of unconventional beauty and
the material covered by the book is unique." (Mathematical Reviews)
