Abstract

Bieberbach's conjecture was very important in the development of Geometric Function Theory, not only because of the result itself, but also due to the large amount of methods that have been developed in search of its proof, it is in this context that the integral transformations of the type fα(z)=0z(f(ζ)/ζ)αdζf_\alpha(z)=\int_0^z(f(\zeta)/\zeta)^\alpha d\zeta or Fα(z)=0z(f(ζ))αdζF_\alpha(z)=\int_0^z(f'(\zeta))^\alpha d\zeta appear. In this notes we extend the classical problem of finding the values of αC\alpha\in\mathbb{C} for which either fαf_\alpha or FαF_\alpha are univalent, whenever ff belongs to some subclasses of univalent mappings in D\mathbb D, to the case of logharmonic mappings, by considering the extension of the \textit{shear construction} introduced by Clunie and Sheil-Small in \cite{CSS} to this new scenario.
