PREFACE
This volume contains papers presented at the summer conference in honor of the sixtieth birthdays of Professors H.-J. Borchers, N. M. Hugenholtz, R. V. Kadison and D. Kastler held at the University of Iowa from June 17 through 21, 1985. The conference did not attempt to cover all subspecialties within operator algebras, let alone mathematical physics, rather it focused on some operator algebraic developments which are of interest to students and research workers in pure as well as in applied areas of mathematics. Special attention is given to an overview of the algebraic approach to quantum field theory, and, in particular, to quantum statistical mechanics. The individual papers are to a large extent self-contained. More than half of the papers culminate with presentations of new results which have not appeared previously in journals. With a few exceptions, these new results are presented with complete proofs. The other half of the papers are devoted to a review of developments in the subject since the 1980 Summer Institute in Kingston.
The material should be accessible to a relatively wide audience, including graduate students and research workers in a broad spectrum of mathematics and mathematical physics: Functional analysis, operator algebras, operator theory, differential geometry, cyclic cohomology, K-theory, and index theory are applied to questions in the quantum theory of fields and statistical mechanics. While the reader should have some familiarity with basic concepts from functional analysis and opera tor theory (at the level of the first volume of the book series by Kadison and Ringrose, the first two chapters of Bratteli-Robinson, or volume one of Reed-Simon), no physics background is assumed.

Xll PREFACE
The past two decades have witnessed a fruitful interaction between operator algebras and mathematical physics. This development is given a systematic and up-to-date treatment.
While the conference emphasized connections between different branches of mathematics and mathematical physics as they connect to operator algebras, we have found it convenient to divide the papers into eight subject groups. It is in the nature of the material that the division line between the different groups (making up separate chapters) is not a sharp one, and, in some cases, a given paper might be considered as belonging to two or more subject categories.
We should like to stress that these proceedings contain material covered in one form or another at the conference. A number of researchers were invited and could not come, and their results unfortunately are not included. Someone could have been overlooked when invitations were mailed out, and the organizers want to apologize in advance for such oversights.
The editors and conference organizers wish to thank the National Science Foundation and the University of Iowa for generous financial support, and for help and encouragement in the planning phase. We also wish to thank the Departments of Mathematics and Physics at the University of Iowa for facilities and support. The American Mathematical Society, and Ms. M. C. Almeida in the production department, have been very helpful in the production of this book. We are pleased to record our gratitude. Last, but not least, thanks are due to the participants and speakers for making the conference possible.
