On an identity theorem in the Nevanlinna class $${\mathcal N}$$. (English) Zbl 0804.30031
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 $$N$$.
