Coefficient estimates for functions associated with vertical strip domain

Serap Bulut

Kocaeli University

Abstract

In this paper, we consider a convex univalent function $f_{alpha ,eta }$ which maps the open unit disc $mathbb{U}$ onto the vertical strip domain egin{equation*} Omega _{alpha ,eta }=left{ win mathbb{C}:alpha

Keywords: Analytic and univalent function, bi-univalent function, close-to-convex function, starlike function, subordination principle, Fekete-Szeg"{o} problem
