One-sided cluster sets of boundary values of analytic functions. (English) Zbl 1104.30002

Summary: We study the one-sided cluster sets of the boundary values of bounded analytic functions and show that even though they can be disjoint, they cannot be contained in the unbounded component of the complement of the other. Using results in this direction, we are able to prove that for distributional boundary values of analytic functions, the existence of one-sided distributional values in the sense of Campos Ferreira implies their equality and the existence of the distributional value.
