On a new subclass of p-valent functions with negative coefficients

Bu makalede negative katsayılı p − valent analitik fonksiyonların *( , , , , ) pP α β ξ Ω m ile gösterilen yeni bir sınıfı tanıtıldı. *( , , , , ) pP α β ξ Ω m sınıfına ait fonksiyonlar için katsayı teoremi, distorsiyon teoremi ve kapanış teoremi belirlendi. Ayrıca *( , , , , ) pP α β ξ Ω m sınıfı için konvekslik yarıçapı elde edildi. Bundan başka *( , , , , ) pP α β ξ Ω m sınıfına ait

Negatif katsayılı p-valent fonksiyonların bir yeni altsınıfı hakkında

We introduce a new subclass *( , , , , ) pP α β ξ Ω m of analytic and p − valent functions with negative coefficients. Coefficient theorem, distortion theorem and closure theorem of functions belonging to the class *( , , , , ) pP α β ξ Ω m are determined. Also we obtain radius of convexity for * ( , , , , ). pP α β ξ Ω m Integral operators of functions belonging to the class *( , , , , ) pP α β ξ Ω m are studied here. Furthermore the extreme points of *( , , , , ) pP α β ξ Ω m are also determined.
