Abstract:In this paper, nonlinear integral operators on normalized analytic functions in the unit disk are investigated in connection with the pre-Schwarzian derivative and the Hornich operation. In particular, several nontrivial relations between these operators and the class of strongly starlike functions will be deduced.
Keywords:Univalent function  Integral transform  Hornich operation  Teichmü  ller space
