Discovering Mathematics with Magma: Reducing the Abstract to the Concrete

by Wieb Bosma (Editor), John Cannon (Editor)

Overview

The appearance of this volume celebrates the first decade of Magma, a new computer algebra system launched at the First Magma Conference on Com- tational Algebra held at Queen Mary and Westfield College, London, August 1993. This book introduces the reader to the role Magma plays in advanced mathematical research. Each paper examines how the computer can be used to gain insight into either a single problem or a small group of closely related problems. The intention is to present sufficient detail so that a reader can (a), gain insight into the mathematical questions that are the origin of the problems, and(b), develop an understanding as to how such computations are specified in Magma. It is hoped that the reader will come to a realisation of the important rolethatcomputational algebracanplayinmathematical research. Readers not primarily interested in using Magma will easily acquire the skills needed to undertake basic programming in Magma, while experienced Magma users can learn both mathematics and advanced computational methods in areas related to their own. The core of the volume comprises 14 papers. The authors were invited to submit articles on designated topics and these articles were then reviewed by referees. Although by no means exhaustive, the topics range over a consid- able part of Magma’s coverage of algorithmic algebra:from number theory and algebraic geometry, via representation theory and computational group theory to some branches of discrete mathematics and graph theory. The papers are preceded by an outline of the Magma project, a brief summary of the papers and some instructions on reading the Magma code. A basic introduction to the Magma language is given in an appendix. The editors express their gratitude to the contributors to this volume, both for the work put into producing the papers and for theirpatience.
