Abstract

The principal goal of this paper is to extend the classical problem of finding the values of α∈ℂ for which either fˆ_α(z)=∫₀^z(f(ζ)∕ζ)^αdζ or f_α(z)=∫₀^z(f^′(ζ))^αdζ are univalent, whenever f belongs to some subclasses of univalent mappings in D, to the case of harmonic mappings, by considering the shear construction introduced by Clunie and Sheil-Small in [4].
