Hyperfunctions and Harmonic Analysis on Symmetric Spaces (eBook, PDF)

• Format: PDF

Produktbeschreibung

This book gives an introductory exposition of the theory of hyperfunctions and regular singularities. This first English introduction to hyperfunctions brings readers to the forefront of research in the theory of harmonic analysis on symmetric spaces. A substantial bibliography is also included. This volume is based on a paper which was awarded the 1983 University of Copenhagen Gold Medal Prize.
