Fekete-Szego Problems for Spirallike Mappings and Close-to-Quasi-Convex Mappings on the Unit Ball of a Complex Banach Space
In the first part of this paper, we will give the Fekete-Szego inequality for various subfamilies of spirallike mappings of type beta on the unit ball of a complex Banach space. Our results give extensions of those given by Lai and Xu (Results Math 76(4), Paper No. 191, 2021) and Elin and Jacobzon (Results Math 77(3), Paper No. 137, 2022). We next give the Fekete-Szego inequality for close-to-quasi-convex mappings of type B on the unit ball of a complex Banach space. Our results give extensions of that given by Xu et al. (Complex Var Elliptic Equ. https://doi.org/10. 1080/17476933.2021.1975115).
