                               Workshop
                `OPERATORS, SYSTEMS AND LINEAR ALGEBRA:
               THREE DECADES OF ALGEBRAIC SYSTEMS THEORY'
                  In Honor of Professor Paul Fuhrmann

                       Kaiserslautern, Germany
                        September 24-26, 1997

Dear Colleagues, we would like to invite you to attend a workshop
on `Operators, Systems and Linear Algebra,' which will be held
at the University of Kaiserslautern, September 24-26, 1997.

The scope of the workshop is to present a retrospect of the
past three decades of algebraic systems theory as well as
to provide an outlook on the future development of the field.

The workshop is dedicated to Paul A. Fuhrmann, in acknowledgement
of his major contributions to operator and systems theory, and on
the occasion of his 60th birthday.

Proceedings will be published by Teubner Verlag, in cooperation
with the European Consortium for Mathematics in Industry.

For further information, please contact:
Eva Zerz, Department of Mathematics, University of Kaiserslautern,
67663 Kaiserslautern, Germany. Fax: +49 631 205 3052.

We are looking forward to seeing you in Kaiserslautern!
