Groups and Fourier analysis
Compact Groups Each Chapter Ends groups Each chapter ends exercises with solutions given at the end of the book and historical notes This book which is new to the AMS publishing program is an excellent example of the author's well known clear and careful writing style It has become the standard text for the study of spherical functions and invariant differential operators on symmetric spaces Sigurdur Helgason was awarded the Steele Prize for Groups and Geometric Analysis and the companion volume Differential Geometry Lie Groups and Symmetric Spaces.
helgason's impressive three books on ie groups andimpressive three books on Lie groups and geometry and analysis of symmetric spaces is an introduction to group theoretic methods in analysis on spaces with a group action The first chapter deals with the three two dimensional spaces of constant curvature reuiring only elementary methods and no Lie theory It is remarkably accessible and be suitable for a first year graduate course The remainder
