Title:* Layered resolutions and Cohen-Macaulay approximation*
Abstract: The representation theory of finite-dimensional algebras has an
important generalization to the study of maximal Cohen-Macaulay modules
(MCMs) over local Cohen-Macaulay rings. In the case of a hypersurface
ring,
this is the study of the matrix factorizations of the equation of the
hypersurface, and these come from minimal free resolutions of the MCMs. I
will talk about the "next" case---MCMs and their minimal free resolutions
over complete intersections. This is joint work with Irena Peeva.
