Non-tangential maximal moduli and harmonic functions on the upper half plane (part 2)
Hon Ming Ho, Kin Y. Li · Pure Mathematical Sciences · 2021
In paper [3], we introduce non-tangential maximal moduli to harmonic functions on upper half plane. In this paper, we present a necessary and sufficient condition using non-tangential moduli to characterize real parts of holomorphic functions with their boundary value functions having smoothness of high order.
