PREFACE

The possibility of approaching major problems from diverse points of view is both a gratifying and significant aspect of mathematics.

With this in mind, an International Conference on Several

Complex Variables was organized and held at the University of Maryland, College Park, Maryland, from April 6 through 17, 1970.

This

volume (the first of two) contains some of the papers presented at this Conference.

Hopefully these reports, which represent the ideas

of many mathematicians working in distinct but related fields, will serve both mathematicians and mathematics. The Conference was supported in part by the Air Force Office of Scientific Research (contract number AFOSR­70­l83l) and the Office of Naval Research (contract number NOOOl4­67­A­0239­00l0).

AUTOMORPHIC FORMS WITH INTEGRAL FOURIER COEFFICIENTS Walter L. Baily, Jr.

1

The purpose of this note is to prove that under aertain hypotheses, the graded ring of integral automorphic forms, with respect to an arithmetic group operating on a tube domain, is generated as a graded algebra over the complex numbers by a finite number of automorphic forms having rational integral Fourier coefficients.

The result, which seems to have some potential number-

theoretic interest, was inspired by notes of M. Eichler [8, esp. Satz 49] and by questions
