… In this paper, we investigate harmonic univalent functions convex in the direction 𝜃 , for 𝜃
∈ [0,π) . We find bounds for |f z (z)|, | f z ( z ) | and |f(z)|, as well as coefficient bounds on the
series expansion of functions convex in a given direction. … In this section we study the
class S H 0 ( k , θ ) and find bounds for | f z ( z ) | , | f z ( z ) | and |f(z)| , as well as coefficient
bounds on the series expansion of harmonic quasi conformal mappings that are univalent
and convex in a given direction. As is done in the litrature for Theorems 2.1 and 2.2, let φ …
