The papers deals with a finite moment problem for rational matrix-valued functions. We present a necessary and sufficient condition for the solvability of the problem. In the nondegenerate case we construct a particular solution which has interesting extremal properties.

Let { n } ∞ n=1 be a sequence of points in the open unit disk in the complex plane and let . We put L = span{B n : n = 0, 1, 2, . . .} and we consider the following "moment" problem: Given a positive-definite Hermitian inner product •, • in L, find all positive Borel measures on [-, ) such that We
