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.
