Abstract

Let \(\widehat{\mathcal {S}}_g^{\alpha , \beta }(\mathbb {B}^n)\) be a subclass of normalized biholomorphic map**s defined on the unit ball in \(\mathbb {C}^n,\) which is closely related to the starlike map**s. Firstly, we obtain the growth theorem for \(\widehat{\mathcal {S}}_g^{\alpha , \beta }(\mathbb {B}^n)\). Secondly, we apply the growth theorem and a new type of the boundary Schwarz lemma to establish the distortion theorems of the Fréchet-derivative type and the Jacobi-determinant type for this subclass, and the distortion theorems with g-starlike map** (resp. starlike map**) are partly established also. At last, we study the Kirwan and Pell type results for the compact set of map**s which have g-parametric representation associated with a modified Roper–Suffridge extension operator, which extend some earlier related results.
