Problem Statement

Let us assume that the series of holomorphic functions k=1fk(z) \sum_{k=1}^{\infty}f_k(z) is absolutely convergent for all zC z \in \mathbb{C}. Let HC H \subseteq \mathbb{C} be the set of those points where the above sum funcion is not regular. Prove that H H is nowhere dense but not necessarily countable. L. Kerchy
