From the reviews:
“A good starting point to learn about Helton’s influential work at the edge of Operator theory and systems engineering. … Many of the main topics in this area are covered by the 19 contributions, all written by the main players in the field. … brought in the form of a tutorial, a survey, or even a shorter note, but all very readable and up-to-date. … it can be safely recommended to specialists and to students at an advanced mathematics or engineering level as well.” (A. Bultheel, The European Mathematical Society, September, 2012)Mathematical Methods in Systems, Optimization, and Control
Festschrift in Honor of J. William Helton
herausgegeben von Harry Dym, Mauricio C. de Oliveira und Mihai PutinarThis volume is dedicated to Bill Helton on the occasion of his sixty fifth birthday. It contains biographical material, a list of Bill's publications, a detailed survey of Bill's contributions to operator theory, optimization and control and 19 technical articles. Most of the technical articles are expository and should serve as useful introductions to many of the areas which Bill's highly original contributions have helped to shape over the last forty odd years. These include interpolation, Szegö limit theorems, Nehari problems, trace formulas, systems and control theory, convexity, matrix completion problems, linear matrix inequalities and optimization.
The book should be useful to graduate students in mathematics and engineering, as well as to faculty and individuals seeking entry level introductions and references to the indicated topics. It can also serve as a supplementary text to numerous courses in pure and applied mathematics and engineering, as well as a source book for seminars.
