FeketeSzegö functional for a subclass of starlike functions with respect to symmetric points

Let A be the class of functions analytic in the unit disc E = {z:|z|₁ < 1}. Let S(α) denote the class of functions in A satisfying the condition Re , (0≤α≤1) and zεE. We are interested in determining the upper bounds of the FeketeSzegö functional for functions of the class S(α).
