Pre-Schwarzian norm estimate for certain Ma-Minda class of functions

Abstract Let S * ( φ ) ${\mathcal{S}}^{\ast }(\varphi )$ be the class of all analytic functions f in the unit disk D = { z ∈ C : | z | < 1 } $\mathbb{D}=\left\{z\in \mathbb{C}\,:\,\vert z\vert < 1\right\}$ , normalized by f (0) = f ′(0) − 1 = 0, that satisfy the subordination rel...
