Abstract
In this paper, it is attempted to introduce and
investigate new subclasses of Sakaguchi kind of functions
related to shell – likes curves connected with Fibonacci numbers.
Furthermore, the estimates of first two coefficients of functions
in these classes are obtained. Fekete – Szego inequalities for
these function classes are also determined.
