The origins of the theory of finite fields and its connections with number theory reach back into the 17th and 18th century. In recent decades this subject has been rapidly growing in importance because of its diverse applications in such areas as coding theory, combinatorics, and the mathematical study of switching circuits. This book presents both the classical and the application-oriented aspect of the theory of finite fields.

Chapters 1 and 2 cover the background and the general structure theory of finite fields. Chapters 3 and 4 are devoted to polynomials and factorization algorithms. Chapters 5, 6, and 7 deal with exponential sums, equations, and permutation polynomials. Chapters 8 and 9 are devoted to linear recurring sequence and other applications.

The notes at the end of each chapter are excellent historical surveys. The bibliography is very comprehensive and up to date. This volume can be strongly recommended as the handbook of finite fields. In order to make the book useful as a text for advanced level courses the authors have inserted worked-out examples at appropriate points. These and the exercises at the end of each chapter are well-chosen.
