Abstract

For meromorphic p-valent function of the form fi z = 1−α z−w p + ∑∞ n=2 a i n z− w n , α < 1, which are analytic in the punctured unit disk z : 0 < |z −w| < 1 with a pole of order p at w, a class Γp β ζ1, ζ2; γ is introduced and some properties for Γp α ζ1, ζ2; γ of fi z in relatioon to the coefficient bounds, convex combination and convolution were discussed.

Keywords
