Abstract
In this article we prove that a subset E of the open unit disc U is a dominating set for the subclass N + of the Nevanlinna class N if and only if E is nontangentially dense. When E is a compact subset of U, we also give a complete characterization of E to be a dominating set for the subclass N - . Here N - denotes the proper subclass of N that consists of all of the reciprocal of the singular inner functions.
