On an identity theorem in the Nevanlinna class \({\mathcal N}\)
The author asks the following question: How quickly can the values of a nonconstant function in the Nevanlinna class \(N\) of the disc on \(\{z_ n\}\) approximate an arbitrary number in \(\mathbb{C}\). He gives a result which is an extension of the classical theorem of Blaschke about the zeros of functions in \(N\).
