Coefficients of powers of univalent functions

Complex Variables, Theory and Application: An International Journal, 1986
Let S be the usual class of normalized univalent functions. We write and consider the behaviour of the upper bounds An (λ) of the |an(λ)| for fψ S. If f(z) is the Koebe function an (λ)= bn (λ) where For λ = 1 de Branges has recently proved Bieberbach's conjecture that An (λ)= bn (λ) and his method extends at once to the case λ > 1.
