Introducing a Novel Subclass of Harmonic Functions with Close-to-Convex Properties

Serkan Çakmak, Sibel Yalçin

In this paper, we introduce a new subclass of close-to-convex harmonic functions. We present a sufficient coefficient condition for a function to be a member of this class. Further…

Serkan Çakmak, Elif Yaşar, Sibel Yalçın

In this paper, we introduce a new subclass of harmonic functions in the open unit disk satisfying ${\…

An Application of Jackson's -Derivative to a Subclass of Starlike Functions with Negative Coefficients

Feras Yousef, Amal Al-Shible, Sibel Yalçın

In this paper, we introduce and investigate the subclass of starlike functions with negative coefficients by using the differential operator $Υ_{τ,p…

Construction of Toeplitz Matrices whose elements are the coefficients of univalent functions associated with -derivative operator

Nanjundan Magesh, Şahsene Altınkaya, Sibel Yalçın

In this paper, we find the coefficient bounds using symmetric Toeplitz determinants for the functions belonging to the subclass .

On some subclasses of m-fold symmetric bi-univalent functions

Şahsene Altınkaya, Sibel Yalçın

In this work, we introduce two new subclasses S_{Σ_{m}}(α,λ) and S_{Σ_{m}}(\b{eta},λ) of Σ_{m} consisting of analytic and m-fold symmetric bi-univalent functions in the open unit d…
