Logarithmic coefficients of some close-to-convex functions

Md. Firoz Ali, A. Vasudevarao

摘要:

解析单叶函数$f$在单位圆$\mathbb{D}=\{z\in\mathbb{C}:|z|<1\}$中的对数系数$γ_n$由$\log \frac{f(z)}{z}= 2\sum_{n=1}^{\infty} γ_n z^n$定义。本文考虑了关于奇星形函数的近于凸函数(带辐角$0$),并确定了$f$,$n=1,2,3$的精确上界.

英文摘要:

The logarithmic coefficients $γ_n$ of an analytic and univalent function $f$ in the unit disk $\mathbb{D}=\{z\in\mathbb{C}:|z|<1\}$ with the normalization $f(0)=0=f'(0)-1$ are defined by $\log \frac{f(z)}{z}= 2\sum_{n=1}^{\infty} γ_n z^n$. In the present paper, we consider close-to-convex functions (with argument $0$) with respect to odd starlike functions and determine the sharp upper bound of $|γ_n|$, $n=1,2,3$ for such functions $f$.
