On a subclass of n-p -valent prestarlike functions
The object of this paper is to study the subclass Rp[?,?,n] R p [ ? , ? , n ] of n-p n - p -valent ? ? -prestarlike functions of order ? ? with negative coefficients. Extreme points, integral operators and distortion theorems of this class are obtained. We also obtain some results for the modified Hadamard products of functions belonging to this class.
