Applied and Computational Harmonic Analysis (ACHA)

Applied and Computational Harmonic Analysis is a prestigious interdisciplinary mathematics journal established in 1993 and published bimonthly by Elsevier. It serves as a leading venue for rigorous research at the intersection of harmonic analysis, applied mathematics, and computational methods. The journal’s primary focus is on the development and analysis of mathematical techniques such as wavelet and frame theory, sparse representations, compressive sampling, and multiscale methods, and their application to problems in signal and data processing, image analysis, high-dimensional geometry, and related fields. ACHA aims to bridge theoretical foundations and computational practice, promoting innovative algorithmic solutions backed by deep analytical insights. Its interdisciplinary scope makes it relevant not only to pure mathematicians but also to engineers and computational scientists working on real-world data analysis challenges. The journal’s editorial leadership — including Radu Balan, Ronald R. Coifman, and David Donoho — reflects its high academic standards and global reach, drawing contributions from top researchers worldwide. With a print ISSN of 1063-5203 and electronic ISSN of 1096-603X, Applied and Computational Harmonic Analysis continues to influence developments in harmonic analysis, signal processing, and computational mathematics.
