PREFACE
This volume contains the lecture notes prepared by six speakers for
the American Mathematical Society Short Course on the Mathematics of Infor
mation Processing given in Louisville, Kentucky, January 23-24, 1984. The
Short Course Advisory Subcommittee of the AMS approved this concept and
recommended publication of these lecture notes.
The Mathematics of Information Processing is not a single topic but
rather a collection of methodologies whose end-goal is the creation of
automated information systems.
The viewpoint represented here is largely that of American researchers
with heavy emphasis on the mathematical problems of database systems and
communication networks. This reflects the rapid introduction of the products
of information technology in the workplace and in the home. By way of con
trast a systems-theoretic approach developed in the Soviet Union is included
which also provides a self-contained background should the reader care to
probe more deeply into the subject.
The idea for the Short Course arose while one of us (Anshel) was a
NASA-ASEE Summer Faculty Fellow at Goddard Space Flight Center, NASA. There
we learned of a proposed futuristic information system, IESIS (Intelligent
Earth sensing Information System). The real-world implementation of the
Short Course rested on the shoulders of the practitioner among us (Gewirtz)
who also chaired a lively panel discussion with a surprise guest (Bob Targan).
We would like to thank the speakers for their efforts in the preparation
of these lectures and their patience concerning the idiosyncracies of the
co-director.
Finally we also wish to thank Stefan Burr who acted as wise counsel and
enthusiastic supporter.
