Item Coefficient bounds and distortion theorems for the certain analytic functions(2019) Altintas, Osman; Mustafa, NizamiIn this paper, we introduce and investigate an analytic function class P-q(lambda, A, B) that we call the class of q-starlike and q-convex functions with respect to the parameter lambda. We give coefficient bounds estimates, distortion bound and growth theorems for the functions belonging to this class.Item Coeffiinicet Problems For A Certain Subclass Of Analytic And Univalent Functions(TURKISH JOURNAL OF MATHEMATICS, 2024-11-26) Altintas, Osman; Mustafa, NizamiIn the present work, some new subclasses of analytic and univalent functions are introduced and some geometric properties such as coefficient estimates problem are studied for them. Furthermore, we show that our results are generalization for some earlier work in the literature and we show this by comparing ours with those related.Item Distortion bound and growth theorems for a subclass of analytic functions defiined by $q$-derivative(2022) Altintas, Osman; Mustafa, NizamiIn this study, we introduce and examine a subclasses of analytic and univalent functions defined by q -derivative. Here, we give necessary conditions for the functions to belong to these subclasses, and distortion bound and growth theorems for the functions belonging to these classes.
