Introduction This is a continuation of "Automorphic Forms on

GL (2) ".

Un-

fortunately, the reader (if any) will have to have a serious knowledge of the two first chapters of the first volume if he is to find his way through the second one.

Perhaps reading Godement's

on Jacquet-

Langlands", Institute for Advanced Study (1970) will help him in satisfying this stringent requirement.

The main purpose of the second

volume is to reformulate and extend a classical result:

if

are two Dirichlet series associated with automorphic forms (in the classical sense) then the Dirichlet series \' a bins n n

L

is convergent in some right half space, can be analytically continued in the whole complex plane as a meromorphic function of a suitable functional equation.

s

and satisfies

Anything novel in this work comes from

the point of view which is the theory of group representations.

The

local theory in §14 to 18 is a preparation of a technical nature for the global theory of § 19. the latter section.

The motivations appear therefore only in

The reader should read first §14, take for granted

the results of §16 to §18 and then go to §19. to quadratic extensions.

§20 is an application

Again there is nothing really new in it.

In the Bibliography I have tried to indicate my indebtness to previous authors.

But I could not however acknowledge completely my

indebtness to G. Shimura.

This paper would have never been written

IV if not for a suggestion of his.

In particular, the application to

quadratic extensions of §20 was, after the oral indications he gave to me, a routine exercise. I gratefully acknowledge the support of The City University of New York and the National Science Foundation (GP 27952). to express

my
