Flatness and Torsion in Tensor Powers of Modules over Local Rings


This is a fairly literal transcript of my lectures at the 7th Japan-Vietnam Joint Seminar on Commutative Algebra, held in Quy Nhon, Vietnam, from 12th–16th December 2011. The aim of those lectures was to describe my recent work with Avramov [2] on a conjecture of Vasconcelos [18] concerning the relationship between flatness and torsion in tensor product of… (More)
