Maximal Cohen-Macaulay Approximations and Minimal Free Resolutions over Complete Intersections Eisenbud, David
MCM approximations, introduced by Auslander and Buchweitz, provide interesting invariants of modules over a complete intersection (or more generally a Borenstein ring). I'll explain the (simple) computation of them, and some new observations concerning complete intersections that I've been discussing with Sasha Pavlov and Irena Peeva; we have some conjectures that M2 has played a role in formulating and testing!
