摘要
Let Ω be a simply connected domain in ℂ For a function f holomorphic in Ω let Sn (f, ζ) denote the partial sum of the Taylor development of f with center ζ ∈ Ω. We show that generically overconvergence phenomena of Sn(f, ζ) and their derivatives can occur on the boundary ∂Ω or in parts of it. In the rest of the boundary ∂Ω, the universal function f may be smooth. These parts of the boundary do not have to be connected.
