This self-contained volume in honor of John J. Benedetto examines a wide range of topics in harmonic analysis and related areas. These include frame theory, weighted-norm inequalities, wavelet theory, time-frequency analysis, and sampling theory. Although the scope of the book is broad, chapters are clustered by topic to provide authoritative expositions that will be of lasting interest. The original papers collected here are written by prominent, well-respected researchers and professionals in the field of harmonic analysis. The invited chapters pay tribute to John J. Benedetto’s many achievements and express an appreciation for both the mathematical and personal inspiration he has given to so many students, coauthors, and colleagues. The book is an excellent reference for graduate students, researchers, and professionals in pure and applied mathematics, engineering, and physics.
