This book gives the first systematic exposition of geometric analysis on Riemannian symmetric spaces and its relationship to the representation theory of Lie groups. The book starts with modern integ …

Group-theoretic methods have taken an increasingly prominent role in analysis. Some of this change has been due to the writings of Sigurdur Helgason. This book is an introduction to such methods on s …

The first edition of this book has been out of print for some time and I have decided to follow the publisher’s kind suggestion to prepare a new edition. Many examples with explicit inversion formula …
