In the last two decades Cohen-Macaulay rings and modules have been central topics in commutative algebra. This book meets the need for a thorough, self-contained introduction to the homological and combinatorial aspects of the theory of Cohen-Macaulay rings, Gorenstein rings, local cohomology, and canonical modules. A separate chapter is devoted to Hilbert functions (including ...(展开全部)

The guiding goal behind Cohen's intellectual career, he argues, was...(展开全部)

Did you know that European royalty once used cheetahs to hunt deer, or that caracals can capture birds by leaping six and a half feet straight up into the air from a standing start? Have you ever wondered whether domestic cats really do land on their feet when they fall, or how Canada lynx can stalk their prey in the winter without falling through the deep snow? "Wild Cats of t...(展开全部)

This is a panorama of the topology of simply-connected smooth manifolds of dimension four. Dimension four is unlike any other dimension; it is large enough to have room for wild things to happen, but too small to have room to undo them. For example, only manifolds of dimension four can exhibit infinitely many distinct smooth structures. Indeed, their topology remains the least ...(展开全部)
