    Felix-Klein-Kolloquium, Singularities and Matrix Factorizations, Prof. Dr. D. Eisenbud, University of California, Berkley

    Hilbert's Syzygy Theorem is an assertion about the solution of linear equations with coefficients in the ring of polynomials. A famous result of Auslander, Buchsbaum and Serre asserts that a similar statement characterizes smooth points of algebraic varieties. Thus it is reasonable to hope that the way in which this statement fails might tell us about the character of a singular point.For a singular point of a hypersurface f=0 the failure of the Hilbert Syzygy Theorem can be understood in terms of matrix factorizations---pairs of square matrices A,B of functions that vanish at the singular point, such that AB and BA are equal to f times an identity matrix. This elementary idea has had many applications. I'll describe some of the basic theory and recent progress in extending it beyond the hypersurface case.
