Abstract
In the literature on geometric function theory, we can nd many interesting applications of a variety of convolutionoperators which are de ned by means of a number of special functions and analytic number theory. The main object ofthis paper is to examine two subclasses of multivalent functions of the form f(z) = zp +1X k=p+1akzk;which are analytic in the open unit disc U. We investigate convolution properties and coecient estimates for thesesubclasses.
