Abstract
The main purpose of this article is to present a localization of Forelli's theorem for functions holomorphic along a standard suspension of linear discs. This generalizes one of the main results of [Y.-W. Cho, K.-T. Kim, Functions holomorphic along a pencil of holomorphic discs, J. Geom. Anal. 31 (2021), 10634–10637] and the original Forelli's theorem.
