摘要
Let S be the familiar class of normalized univalent functions in the unit disk. Fekete and Szego proved the well-known result max(f is an element of S) vertical bar a(3) -lambda a(2)(2)vertical bar - 1 + 2e(-2 lambda/(1-lambda)) for lambda is an element of [0, 1]. We investigate the corresponding problem for the class of starlike mappings defined on the unit ball in a complex Banach space or on the unit polydisk in C-n, which satisfies a certain condition.
