## Logarithmic coefficients of some close-to-convex functions

29 Jul 2016  ·  Ali Md. Firoz, Vasudevarao A. ·

The logarithmic coefficients $\gamma_n$ 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 $\log \frac{f(z)}{z}= 2\sum_{n=1}^{\infty} \gamma_n z^n$. 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 $|\gamma_n|$, $n=1,2,3$ for such functions $f$...
