Abstract

Using q-analogue of Salagean operator, we investigate subclass of multivalent functions in the open unit disk ∆ . We obtain 􏰕 z(Dq(Dn f(z)) 􏰖 Fekete-Szego ̋ inequalities for a certain class of analytic functions f satisfying 1 + 1 1 p,q − 1 ≺ Υ (z). Applications of ζ [ p ] q D pn , q f ( z ) our results to certain functions defined by convolution products with a normalized analytic function are given. Moreover, Fekete-Szego ̋ inequalities for certain subclasses of functions defined through Poisson distribution are obtained.
