Download or read book Stable Approximate Evaluation of Unbounded Operators written by Charles W. Groetsch and published by Springer. This book was released on 2006-11-15 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book teams up the spectral theory of bounded linear operators with von Neumann’s theory of unbounded operators to provide a framework for the study of stable methods for the evaluation of unbounded operators. The text presents numerous illustrations of unbounded linear operators that arise in various inverse problems of mathematical physics. It also offers an extensive exposition of background material from the theory of operators on Hilbert space.
