Generalised Second Hankel Determinant For A Class Of Analytic Functions

The purpose of the present paper is to consider some subclasses of generalized Pascu classes of functions with respect to symmetric points and obtain sharp upper bounds for the generalized second Hankel determinant | a²a³- μ a3²| for an analytic function f( z) =z + ∑^∞_n=2 a_nzⁿμ is real and |z| < 1 belonging to these classes.
