Abstract:
Let be an inner function on the upper half-plane, and let be the corresponding model subspace. A nonnegative measurable function is said to be strongly admissible for if there exists a nonzero function with . Certain conditions sufficient for strong admissibility are given in the case where is meromorphic.
