Hankel determinant for functions starlike and convex with respect to symmetric points

Sakaguchi (1959) introduced the class of functions S*s , starlike with respect to symmetric points. In 1977, Das and Singh introduced similar class of functions Cs , convex with respect to symmetric points. Here, upper bound for the functional |a2a4-a23| is attained for functions f(z)=z+ ∑ anzn...
