Abstract: Let C be a simple closed Liapounov contour in the complex plane and A an invertible matrixvalued function on C with bounded measurable entries. There is a wellknown concept of factorization of the matrix function A relative to the Lebesgue space . The notion of local factorization of A relative to at a point in C is introduced. It is shown that A admits a factorization relative to if and only if A admits a local factorization relative to at each point in C. Several problems connected with local factorizations relative to are raised.
