Basic Operator Theory provides an introduction to functional analysis with an emphasis on the theory of linear operators and its application to differential and integral equations, approximation theory, and numerical analysis. A textbook designed for senior undergraduate and...

"Written by two distinguished specialists in both research and education, the book represents an excellent introduction to a subject of increasing power and importance in today's mathematics. It is designed for senior undergraduate and graduate students in mathematics, engineering,...

rii application of linear operators on a Hilbert space. We begin with a chapter on the geometry of Hilbert space and then proceed to the spectral theory of compact self adjoint operators; operational calculus is next presented as a nat- ural outgrowth of the spectral theory...
