  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.
