This edited volume presents a collection of research articles written in honor of Akram Aldroubi that highlight his profound and enduring influence on multiple areas of modern analysis and its applications. Written by leading mathematicians, these articles address recent advances in sampling theory, frame theory, wavelet analysis, signal and image processing, data science, and other areas of applied and computational harmonic analysis.
