چکیده
|
By considering a fixed point in the punctured unit disk and using the q–derivative , a new subfamily of meromorphic and univalent functions is defined. also, the first and second order q–derivative of mero-morphic functions are introduced. coefficient bounds, extreme points, radii of starlikeness and convexity are obtained. furthermore, the con-vexity and preserving under convolution with some restrictions on pa-rameters are investigated.
