Fekete-Szeg? Functional for some Subclass of Non-Bazilevic Functions

摘要

In this present investigation, the authors obtain a sharp Fekete-Szeg?'s inequality for certain normalized analytic functions defined on the open unit disk for which lies in a region starlike with respect to and is symmetric with respect to the real axis. Also, certain applications of our results for a class of functions defined by convolution are given. As a special case of this result, Fekete-Szeg?'s inequality for a class of functions defined through fractional derivatives is also obtained.
