Coefficient Bounds for Certain Subclasses of Close-To-Convex Functions of Complex Order

Abstract

In this paper, we determine the coefficient bounds for functions in certain
subclasses of close-to-convex functions of complex order, which are introduced here by means of a certain non-homogeneous Cauchy-Euler-type
differential equation of order $m$. Relevant connections of some of the
results obtained with those in earlier works are also provided.
