On a Subclass of Analytic Functions Related to a Hyperbola

الملخص EN

The object of the present investigation is to solve Fekete-Szegö problem and determine the sharp upper bound to the second Hankel determinant for a new class ℛ̃(a,c,ρ) of analytic functions in the unit disk.

We also obtain a sufficient condition for an analytic function to be in this class.
