On Special Differential Subordinations Using Fractional Integral of Sălăgean and Ruscheweyh Operators
Alina Alb Lupaş, Georgia Irina Oros
Abstract
In the present paper, a new operator denoted by Dz−λLαn is defined by using the fractional integral of Sălăgean and Ruscheweyh operators. By means of the newly obtained operator, the subclass Snδ,α,λ of analytic functions in the unit disc is introduced, and various properties and characteristics of this class are derived by applying techniques specific to the differential subordination concept. By studying the operator Dz−λLαn, some interesting differential subordinations are also given.
