Mellin Analysis, Transform Theory, and Applications: A Self-Contained Approach

This monograph presents the theory of the Mellin transform and the resulting Mellin analysis in a rigorous and unified manner. Often dismissed as a subordinate topic within Fourier and Laplace transform, it is instead demonstrated here that the theory is completely independent, can be studied within a self-contained framework, and exhibits some typical characteristics.

In addition to highlighting the foundations of the theory, the book addresses applications to certain partial differential equations, sampling theory and numerical quadrature. These applications provide methods which are in turn of interest in various areas of mathematics, science, and engineering.

Each chapter is enriched by numerous references to further literature and potential research directions. Researchers working in this field will gain new insights and appreciate the deserved attention for this underrated topic in harmonic analysis.

Paul L. Butzer, born in the Rhein-Ruhr district of Germany, had to leave with his parents and brother for Britain in 1937, lived there for four years, traveled on to Montreal, Canada, studying there, then at the University of Toronto, receiving his Masters degree in 1949, his Ph.D 1951. After teaching at McGill University, Montreal, he returned to Germany in 1955, teaching at the universities of Mainz, Freiburg and Wuerzburg. In 1958 he received an offer to join the RWTH AACHEN, as ordinary professor of mathematics ever since 1961, as Chair Professor in Analysis for 32 years, Prof. Emeritus in 1993. His fields of research include real analysis, approximation theory, functional analysis, operator theory, integral transform theory, signal analysis and prediction theory, combinatorial number theory, probability theory, history of mathematics and in certain areas of astronomy. He published ca. 400 research papers, co-authored some 25 books in a variety of fields, including conference proceedings, from Oberwolfach, Aachen,Yugoslavia, Kuwait. According to the ranking of Research.com, he belonged in the year 2023 to the 1460 best scientists worldwide. He was named a 2024 top scholar by Scholar GPS, ranking him within the top 0.5% of all scholars worldwide. For his lifetime career in all fields he was rated #49,965 overall (all fields ), #11,031 in physical science and maths, #1,118 in maths, and #6 in Fourier analysis.
