Further Geometric Properties of the Barnes–Mittag-Leffler Function
Axioms, 2023 In this paper, we find sufficient conditions to be imposed on the parameters of a class of functions related to the Barnes–Mittag-Leffler function that allow us to conclude that it possesses certain geometric properties (such as starlikeness, uniformly ...

On q-Starlike Functions Defined by q-Ruscheweyh Differential Operator in Symmetric Conic Domain
Symmetry, 2021 Motivated by q-analogue theory and symmetric conic domain, we study here the q-version of the Ruscheweyh differential operator by applying it to the starlike functions which are related with the symmetric conic domain.

Radii of Starlikeness Associated with the Lemniscate of Bernoulli and the Left-Half Plane
, 2011 A normalized analytic function f defined on the open unit disk in the complex plane is in the class SL if zf'(z)/f(z) lies in the region bounded by the right-half of the lemniscate of Bernoulli given by |w^2 - 1| < 1. In the present investigation, the SL-

Multivalent Harmonic Uniformly Starlike Functions [PDF]
Kyungpook mathematical journal, 2009 Summary: We investigate a family of generalized complex-valued harmonic functions that are multivalent, sense-preserving, and which are associated with \(k\)-uniformly harmonic functions in the unit disk. The obtained results include a number of known and new results as special cases.

Spirallikeness of shifted hypergeometric functions
, 2016 In the present paper, we study spirallikenss (including starlikeness) of the shifted hypergeometric function $f(z)=z_2F_1(a,b;c;z)$ with complex parameters $a,b,c,$ where $_2F_1(a,b;c;z)$ stands for the Gaussian hypergeometric function. First, we observe

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.

Bohr Radius Problems for Some Classes of Analytic Functions Using Quantum Calculus Approach
Mathematics, 2020 The main purpose of this investigation is to use quantum calculus approach and obtain the Bohr radius for the class of q-starlike (q-convex) functions of order α . The Bohr radius is also determined for a generalized class of q-Janowski starlike and
