Spherical Inversion on SLn(r)

About this book

"Harish-Chandra's general Plancherel inversion theorem admits a much shorter presentation for spherical functions. The authors have taken into account contributions by Helgason, Gangolli, Rosenberg, and Anker from the mid-1960s to 1990. Anker's simplification of spherical inversion on the Harish-Chandra Schwartz space had not yet made it into a book exposition. Previous expositions have a dealt with a general, wide class of Lie groups. This has made access to the subject difficult for outsiders, who may wish to connect some aspects with several if not all other parts of mathematics, and do so for specific cases of intrinsic interest. The essential features of Harish-Chandra theory are exhibited on SL[subscript n](R), but hundreds pages of background can be replaced by short direct verifications. The material becomes accessible to graduate students with essentially no background in Lie groups and representation theory. Spherical inversion is sufficient to deal with the heat kernel, which is at the center of the authors' current research. The book will serve as a self-contained background for parts of this research."--BOOK JACKET.
