Trends in Commutative Algebra (Hardcover)

In 2002, an introductory workshop was held at the Mathematical Sciences Research Institute in Berkeley to survey some of the many new directions of the commutative algebra field. Six principal speakers each gave three lectures, accompanied by a help session, describing the interaction of commutative algebra with other areas of mathematics for a broad audience of graduate students and researchers. This book is based on those lectures, together with papers from contributing researchers. David Benson and Srikanth Iyengar present an introduction to the uses and concepts of commutative algebra in the cohomology of groups. Mark Haiman considers the commutative algebra of n points in the plane. Ezra Miller presents an introduction to the Hilbert scheme of points to complement Professor Haiman's paper. David Eisenbud and Jessica Sidman give an introduction to the geometry of syzygies, addressing the basic question of relating the geometry of a projective variety with an embedding into projective space to the minimal free resolution of its coordinate ring over the polynomial ring of ambient projective space. Melvin Hochster presents an introduction to the theory of tight closure. to compute it. Rob Lazarsfeld and Manuel Blickle discuss the theory of multiplier ideals and how they can be used in commutative algebra. Bernard Teissier presents ideas related to resolution of singularities, complemented by Ana Bravo's paper on canonical subalgebra bases.
