Abstract
In this chapter we solve the interpolation problem with given null-pole subspace for the case where no data is prescribed at infinity. The construction is based on the interpolation theorems from Part I. The interpolation theorems in Chapters 6 and 7 for J-unitary matrix functions lead to indefinite metric versions of the Beurling-Lax theorem for rational matrix functions.
