Inequalities of a Class of Analytic Functions Involving Multiplicative Derivative
MathematicsUsing the concepts of multiplicative calculus and subordination of analytic functions, we define a new class of starlike bi-univalent functions based on a symmetric operator, which involved the three parameter Mittag-Leffler function.

Univalent functions defined by Ruscheweyh derivatives
International Journal of Mathematics and Mathematical Sciences, 1983 We study some radii problems concerning the integral operator F(z)=γ+1zγ∫°zuγ−1f(u)du for certain classes, namely Kn and Mn(α), of univalent functions defined by Ruscheweyh derivatives. Infact, we obtain the converse of Ruscheweyh's result and improve

Some Evaluations About Coefficients Boundaries for Specific Classes of Bi-Univalent Functions
AxiomsNew subclasses of bi-univalent functions with bounded boundary rotation are presented in this study. We acquired estimates for the initial coefficients a2, a3 and a4.

Journal of Function Spaces, 2018 This article deals with q-starlike functions associated with conic domains, defined by Janowski functions. It generalizes the recent study of q-starlike functions while associating it with the conic domains.

Some general families of q-starlike functions associated with the Janowski functions
Filomat, 2019 By making use of the concept of basic (or q-) calculus, various families of q-extensions of starlike functions, which are associated with the Janowski functions in the open unit disk U, were introduced and studied from many different viewpoints and ...

On the non-starlikeness of solutions to the starlike interior wake problem [PDF]
Proceedings of the American Mathematical Society, 2005 We study examples of the starlike interior “wake problem" for which no starlike solution exists relative to the natural star center of the problem. These examples show that the main result of D.E. Tepper in “A mathematical model for a wake” (Michigan Math. J. 31 (1984), 161–165) is not correct.

A Subclass of Analytic Functions Related to k-Uniformly Convex and Starlike Functions
Journal of Function Spaces, 2017 We investigate some subclasses of k-uniformly convex and k-uniformly starlike functions in open unit disc, which is generalization of class of convex and starlike functions.

Close-to-starlike logharmonic mappings
International Journal of Mathematics and Mathematical Sciences, 1996 We consider logharmonic mappings of the form f=z|z|2βhg¯ defined on the unit disc U which can be written as the product of a logharmonic mapping with positive real part and a univalent starlike logharmonic mapping.
