Some inclusion relations between various subclasses of planar harmonic mappings involving confluent hypergeometric distribution series
(Işık University Press, 2019)
The purpose of the present paper is to establish connections between various subclasses of harmonic univalent functions by applying certain convolution operator involving Confluent Hypergeometric distribution series. To ...
Subclasses of univalent functions related with functions of bounded radius rotation
(Işık University Press, 2023-04)
This investigation is in twofold. Firstly, a comprehensive generalization of starlike functions is initiated. This notion gives more insight to the study of functions with bounded radius rotation. In this direction, we ...
Certain subclasses of analytic function by S?l?gean q-differential operator
(Işık University Press, 2023-01)
The theory of q-analysis has many applications in various sub-fields of mathematics and quantum physics. In the present article, we define the class Tn(?, ?; q) using the S?l?gean q-differential operator. For functions ...

In this paper, we obtain some sufficient conditions for generalized Sakaguchi type function of order ?, defined on the open unit disk. Many interesting outcomes of our results are also calculated.
Initial bounds for certain classes of bi-univalent functions defined by the (p, q)-lucas polynomials
(Işık University Press, 2021)
Our present investigation is motivated essentially by the fact that, in Geometric Function Theory, one can find many interesting and fruitful usages of a wide variety of special functions and special polynomials. The main ...

(Işık University Press, 2023-10)
Making use of S?l?gean differential operator, in this paper, we introduce and investigate an interesting subclass Sh,p? (k, ?) of bi-univalent functions in the open unit disk U. Furthermore, we find estimates on the |a2| ...
Sharp inequalities for univalence of meromorphic functions in the punctured unit disk
(Işık University Press, 2021)
A new class of meromorphic functions f that are univalent in the punctured unit disk U? = {z : 0 < |z| < 1} is introduced. This class is denoted by MU and consisting of functions f defined by |1 + f’(z)/f ²(z)| < 1 and ...
On the Chebyshev polynomial coefficient problem of bi-Bazilevi? functions
(Işık University Press, 2020)
A function said to be bi-Bazilevi? in the open unit disk U if both the function and its inverse are Bazilevi? there. In this paper, we will study a newly constructed class of bi-Bazilevi? functions. Furthermore, we establish ...
Applications of chebyshev polynomials on ?-pseudo bi-starlike and ?-pseudo bi-convex functions with respect to symmetrical points
(Işık University Press, 2020)
The purpose of this work is to use the Chebyshev polynomial expansions to seek upper bounds for the second and third coefficients of functions belongs to a subclass of ?-pseudo bi-starlike and ?-pseudo bi-convex functions ...
