摘要:In the present paper, sharp upper bounds of |a 3 − µa 2 2 | for the functions f(z) = z+a 2 z 2 +a 3 z 3 +··· belonging to a new subclass of Sakaguchi type functions are obtained. Also, application of our results for subclass of functions defined by convolution with a normalized analytic function are given. In particular, Fekete-Szegö inequalities for certain classes of functions defined through fractional derivatives are obtained.
