A correct proof of logarithmic coefficients for Janowski type $(j, k)$ -symmetric starlike functions

Navneet Lal Sharma

Recently, authors [7] studied the logarithmic coefficient bounds for class of the Janowski type $(j, k)$ -symmetric starlike functions $S T_{[j, k]} (A, B)$ in ({\em Rev. Real…

Logarithmic coefficients of the inverse of univalent functions

S. Ponnusamy, N. L. Sharma, K. -J. Wirths

Let $\es$ be the class of analytic and univalent functions in the unit disk $∣ z ∣ < 1$ , that have a series of the form $f (z) = z + \sum_{n = 2}^{\infty} a_{n} z^{n}$ . Let $F$ be the inverse of t…

Logarithmic coefficients problems in families related to starlike and convex functions

S. Ponnusamy, N. L. Sharma, K. -J. Wirths

Let $\es$ be the family of analytic and univalent functions $f$ in the unit disk $\D$ with the normalization $f (0) = f^{'} (0) - 1 = 0$ , and let $γ_{n} (f) = γ_{n}$ denote the logarithmic coefficie…
