Abstract:
The object of the present paper is to derive several inequalities
associated with differential subordinations between analytic functions
and a linear operator defined for a certain family of p-valent
functions, which is introduced here by means of a family of extended
multiplier transformations. Some special cases and consequences of
the main results are also considered.

Abstract:
In this present investigation, the authors obtain Fekete-Szegö inequality for a certain class of analytic functions f(z) for which lies in a region starlike with respect to 1 and symmetric with respect to the real axis. Also certain application of our main result for a class of functions defined by Hadamard product (convolution) is given. As a special case of our result we obtain Fekete-Szegö inequality for a class of functions defined through fractional derivatives. Also we obtain Fekete-Szegö inequality for the inverse functions.

Abstract:
In this present investigation, the authors obtainFekete-Szegő's inequality for certain normalized analytic functions defined on the open
unit disk for which lie in a region starlike with
respect to 1 and symmetric with respect
to the real axis. Also certain applications of the main result for a class of functions
defined by convolution are given. As a special case of this result, Fekete-Szegő's inequality for a class of functions
defined through fractional derivatives is also obtained.
