ON CERTAIN CLOSE-TO-CONVEX FUNCTIONS

Bulletin of the Australian Mathematical Society, 2023
AbstractLet $\mathcal {K}_u$ denote the class of all analytic functions f in the unit disk $\mathbb {D}:=\{z\in \mathbb {C}:|z|<1\}$ , normalised by $f(0)=f'(0)-1=0$ and satisfying $|zf'(z)/g(z)-1|<1$ in $\mathbb {D}$ for some starlike function g.

On $\alpha$-close-to-convex functions

Publicationes Mathematicae Debrecen, 1996
Inspired by a paper of \textit{A. W. Goodman} and \textit{E. W. Saff} [Int. J. Math. Math. Sci. 1, 125-132 (1978; Zbl 0383.30005)], the authors investigate the classes \({\mathcal G}_\alpha\) \((-\pi ...

ON OZAKI CLOSE-TO-CONVEX FUNCTIONS

Bulletin of the Australian Mathematical Society, 2018
Let $f$ be analytic in $\mathbb{D}=\{z\in \mathbb{C}:|z|<1\}$ and given by $f(z)=z+\sum _{n=2}^{\infty }a_{n}z^{n}$. We give sharp bounds for the initial coefficients of the Taylor expansion of such functions in the class of strongly Ozaki close-to-convex functions, and of the initial coefficients of the inverse function, together with some growth ...

Weakly Close-to-Convex Meromorphic Functions

Canadian Journal of Mathematics, 1989
Classes of functions, meromorphic and univalent inΔ = {z:|z|< 1}with simple pole at z = p, 0 < p < 1, have been discussed in several places in the literature ([3], [6], [8], [10], [11], and [12]). The purpose of this paper is to discuss a class of Close-to-Convex functions with pole at p analogous to the class of Close-to-Convex functions with

A subclass of close-to-convex functions

Summary: We obtain coefficient estimates and distortion and growth theorems for certain subclass of close-to-convex functions. The results presented here contain those given in earlier works in some special cases.
