This book provides careful and detailed introductions to some of the
latest advances in three significant areas of rapid development in
commutative algebra and its applications. The book is based on courses at
the Winter School on Commutative Algebra and Applications held in
Barcelona: Tight closure and vector bundles, by H. Brenner; Combinatorics
and commutative algebra, by J. Herzog; and Constructive desingularization,
by O. Villamayor.

The exposition is aimed at graduate students who have some experience with
basic commutative algebra or algebraic geometry but may also serve as an
introduction to these modern approaches for mathematicians already
familiar with commutative algebra.

This book is published in cooperation with Real Sociedad Matemática Española (RSME)
