Abstract

In this study, the connection between certain subfamilies of harmonic univalent functions is established by utilizing a convolution operator involving the Mittag–Leffler function. The investigation reveals inclusion relations concerning harmonic γ -uniformly starlike mappings in the open unit disc, harmonic starlike functions and harmonic convex functions, highlighting the improvements given by the results presented here on previously published outcomes.

Subjects
UNIVALENT functions
Abstract

The purpose of this paper is to find new inclusion relations of the harmonic class HF (ϱ , γ) with the subclasses S HF * , K HF and T N HF (τ) of harmonic functions by applying the convolution operator Θ (ℑ) associated with the Mittag-Leffler function. Further for ϱ = 0 , several special cases of the main results are also obtained. [ABSTRACT FROM AUTHOR]

Abstract

Bu çalışmada birim disk içinde tanımlı analitik ve m-katlı simetrik, bi-ünivalent fonksiyonlardan oluşan iki yeni alt sınıf ele alınmıştır. Ayrıca ele alınan bu sınıflar için kesin olmayan 1 ma  ve 21 ma  başlangıç katsayı sınırları elde edilmiştir. En son kısmında ise bu sonuçlar ile yakından ilişkili ve daha önce çalışılmış olan bazı sonuçlara yer verilmiştir. Bu sonuçlardan da anlayabiliriz ki bulduğumuz tahminler daha önce var olan bazı katsayı tahminlerinin bir genellemesidir., In this work, we consider two new subclasses of function class consisting of analytic and m-fold symmetric bi-univalent functions in the open unit disc U. Furthermore, for functions in each of the subclasses introduced in the present investigation, we obtain non-sharp bounds on the initial coefficients 1ma  and 21 ma  . Lastly, several closely-related earlier known results are indicated in the form of corollaries. This shows that, in certain cases, our estimates improve some of those existing coefficient bounds.

Author

Subjects
*UNIVALENT functions, *SYMMETRIC functions
Abstract

We consider two new subclasses S∑m(τ,λ,α)and S∑m(τ,λ,β)of ∑mconsisting of analytic and m-fold symmetric bi-univalent functions in the open unit disk U. Furthermore, we establish bounds for the coefficients of functions in these subclasses andseveral related classes are also considered. In addition to these, connections to earlier known results are presented. [ABSTRACT FROM AUTHOR]
