Coefficients of powers of univalent functions
Complex Variables, Theory and Application: An International Journal, 1986Let 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.

Power series with i.i.d. coefficients
Statistics & Probability Letters, 2013Abstract In this work we consider a power series of the form X = ∑ j = 0 ∞ δ j Z j where 0 δ 1 and { Z j } j ≥ 0 is an i.i.d. sequence of random variables. We show that X is well-defined iff E [ ( log | Z 0 | ) + ] ∞ and establish a ...
