THIRD HANKEL DETERMINANT FOR A CLASS OF ANALYTIC FUNCTIONS WITH RESPECT TO SYMMETRIC POINTS

2015 Acta Universitatis Apulensis  
This paper is concerned with the estimate of second Hankel determinant for the classes of analytic functions whose derivative has a positive real part, analytic functions with respect to conjugate points and with respect to symmetric conjugate points in the unit disc U = {z : |z| < 1}. AMS Subject Classification: 30C45 Key Words: analytic functions, starlike functions, convex functions, functions whose derivative has a positive real part, starlike functions with respect to conjugate points,
