# Euler Products and Eisenstein Series

Share this page
*Goro Shimura*

A co-publication of the AMS and CBMS

This volume has three chief objectives: 1) the determination of local Euler
factors on classical groups in an explicit rational form; 2) Euler products and
Eisenstein series on a unitary group of an arbitrary signature; and 3) a class
number formula for a totally definite hermitian form. Though these are new
results that have never before been published, Shimura starts with a quite
general setting. He includes many topics of an expository nature so that the
book can be viewed as an introduction to the theory of automorphic forms of
several variables, Hecke theory in particular. Eventually, the exposition is
specialized to unitary groups, but they are treated as a model case so that the
reader can easily formulate the corresponding facts for other groups.

There are various facts on algebraic groups and their localizations that are
standard but were proved in some old papers or just called "well-known". In
this book, the reader will find the proofs of many of them, as well as
systematic expositions of the topics. This is the first book in which the Hecke
theory of a general (nonsplit) classical group is treated. The book is
practically self-contained, except that familiarity with algebraic number
theory is assumed.

#### Readership

Graduate students and research mathematicians interested in automorphic forms, zeta functions and/or algebraic groups over global and local fields.

#### Reviews

There is plenty in this volume for both the beginner and the expert. Shimura's book is the first to treat the Hecke theory of general non-split classical groups.
