Duals and dual hulls of classes of analytic functions

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/77531In the paper new representations are obtained for duals and dual hulls of the classes of analytic functions. The Ruscheweyh duality principle is shown to hold under somewhat weaker assumptions. For a compact class of functions its subclass is constructed having the same dual as the original one.10 pages, LaTeX 2.09, to appear in Izvestiya vuzov.
