# Finite Fields: Theory, Applications and Algorithms

*Ronald C. Mullin; Gary L. Mullen*

The Fourth International Conference on "Finite Fields: Theory, Applications,
and Algorithms" was held at the University of Waterloo in August 1997. This
volume presents the refereed proceedings.

Because of its applications in so many diverse areas, finite fields continues to
grow in importance in modern mathematics. Finite fields now play particularly
important roles in number theory, algebra, and algebraic geometry. They also
play a crucial role in computer science, statistics, and engineering. Areas of
application include but are not limited to algebraic coding theory, cryptology,
and combinatorial design theory. Computational and algorithmic aspects of
finite field problems are also growing in significance.

The conference drew workers in theoretical, applied, and algorithmic finite
field theory. All papers were refereed. They are loosely classified as
theoretical and applied and are listed under these general headings. The work
contains up-to-date results from leading experts in the field.
