Starlike symmetrical functions
(Işık University Press, 2020)
The objective of the present paper is to study subclass S ⁽ ʲ̛ ᵏ⁾ (A, B) of analytic functions that is defined by using the class of Janowski functions combined with the (j, k)-symmetrical functions. This class generalizes ...
Neighbourhoods of a certain subclass of strongly starlike functions
(Işık University Press, 2020)
In this paper we introduce and study a new subclass of strongly starlike functions of order α defined by convolution structure. We investigate neighbourhoods and coefficient bounds of this class.
Subclasses of multivalent functions of complex order associated with sigmoid function and bernoulli lemniscate
(Işık University Press, 2020)
In this present work, subclasses of multivalent functions of complex order associated with simple logistic sigmoid activation function and Bernoulli Lemniscate were investigated. Early few coefficient bounds, relevant ...
Convolutions of a subclass of harmonic univalent mappings
(Işık University Press, 2020)
The main object of this paper is to investigate the convolution of a subclass of harmonic univalent mappings which is denoted by fa and generalized harmonic univalent mapping which is denoted by Pc. We obtained Pc ∗ fa is ...
Study of subclasses of starlike and convex functions
(Işık University Press, 2020)
In this article, we introduce new subclasses of starlike and convex functions by using a new differential operator defined in the open unit disk U. We study the geometric properties of such subclasses of starlike and convex ...
An application of (p, q)-calculus in harmonic univalent functions
(Işık University Press, 2020)
The main aim of this paper is to define a (p, q)-multiplier transformation for harmonic functions. Using that we obtain coefficient inequality, extreme points, distortion theorem and covering results for the new subclass ...
On a class of sakaguchi functions related to Bernoulli lemniscate and modified sigmoid function
(Işık University Press, 2020)
The aim of this investigation is to provide further results on a class of Sakaguchi functions related to Bernoulli Lemniscate and modified sigmoid function for the class SL(s, t, Φm,n). Early few coefficient bounds of f(z) ...
