The Algebraic Theory of Modular Systems
by Francis Sowerby Macaulay
Publisher: Cambridge University Press 1916
Number of pages: 140
Many of the ideas introduced by F.S. Macaulay in this classic book have developed into central concepts in what has become the branch of mathematics known as Commutative Algebra. Today his name is remembered through the term 'Cohen-Macaulay ring'.
