Extremal problems for harmonic mappings from the unit disc to convex regions
Orientation preserving harmonic mappings from the unit disc to bounded convex regions are considered `optimally', in the sense that a certain linear functional is optimized. Sharp estimates for the Fourier coefficients of boundary values of such mappings are derived. This work is a continuation of the author's paper in Math. Nachr. 69, 173-190 (1975; Zbl 0277.52010).
