Integral Closure of Ideals, Rings, and Modules

Integral Closure of Ideals, Rings, and Modules

by Irena Swanson and Craig Huneke

Integral Closure of Ideals, Rings, and Modules, with Craig Huneke, published by Cambridge University Press, Cambridge, 2006. This is a graduate-level textbook, and it is also meant to be a reference for researchers. We assume some basic background in commutative algebra, such as completions.
