On the representation of regular functions by Dirichlet series in a closed disk

Yu. I. Mel'nik


Abstract: In this paper it is shown that every function regular in a disk, whose second derivative satisfies a Lipschitz condition of order $\frac12+\alpha$ ($\alpha>0$) on the boundary of the disk, can be expanded as a Dirichlet series which is absolutely and uniformly convergent in the closed disk.
