Results on Univalent Functions Defined by q-Analogues of Salagean and Ruscheweh Operators
In this paper, we define and discuss properties of various classes of analytic univalent functions by using modified q-Sigmoid functions. We make use of an idea of Salagean to introduce the q-analogue of the Salagean differential operator. In addition, we derive families of analytic univalent functions associated with new q-Salagean and q-Ruscheweh differential operators. In addition, we obtain coefficient bounds for the functions in such new subclasses of analytic functions and establishdoi:10.3390/sym14081725 fatcat:ntqwpzyknzdahpf7cxgw3yoqly
