Book DetailsGraduate Studies in MathematicsVolume: 87; 2007; 282 ppMSC: Primary 13; 14; Secondary 55;
This book is aimed to provide an introduction to local cohomology which takes cognizance of the breadth of its interactions with other areas of mathematics. It covers topics such as the number of defining equations of algebraic sets, connectedness properties of algebraic sets, connections to sheaf cohomology and to de Rham cohomology, Gröbner bases in the commutative setting as well as for \(D\)modules, the Frobenius morphism and characteristic \(p\) methods, finiteness properties of local cohomology modules, semigroup rings and polyhedral geometry, and hypergeometric systems arising from semigroups.
The book begins with basic notions in geometry, sheaf theory, and homological algebra leading to the definition and basic properties of local cohomology. Then it develops the theory in a number of different directions, and draws connections with topology, geometry, combinatorics, and algorithmic aspects of the subject.
ReadershipGraduate students and research mathematicians interested in theory and applications of local cohomology.

It's all terrific stuff. I hope this book will succeed in bringing many young mathematicians to love cohomology, too, and then to go on from there.
MAA Reviews 
...this book is an excellent text on local cohomology and complements well the existing sources. It will surely become a standard reference on this theory.
