Results of special type for subclasses of analytic functions

الملخص EN

A subclass of normalized analytic functions symmetric with respect to points is introduced.

The second, the third and the fourth coefficients bounds are obtained.

The Fekete-Szego inequality for a univalent normalized functions f in the subclass is obtained and Hankal determinant inequalities are estimated.

The solution Is given for some values of a constant for the differential equation
