Subclasses of analytic functions of complex order defined by q-derivative operator

Rekha Srivastava, Hanaa Zayed

Abstract


By making use of the q-derivative operator in conjunction with the principle of subordination between analytic functions, we introduce two subclasses of analytic functions in the open unit disk U. We investigate convolution properties and coefficient estimates for these subclasses.

Keywords


Analytic functions; Univalent functions; Hadamard product (or convolution); Subordination between analytic functions; q-Derivative operator
