    In this paper, we investigate certain subclasses of analytic functions defined by generalized differential operators involving binomial series. Also, we obtain coefficient estimates involving of the nonhomogeneous Cauchy-Euler differential equation of order r.

    Some properties of certain multivalent harmonic functions
    (MDPI, 2023-05-23) Oros, Georgia Irina; Yalçın, Sibel; Bayram, Hasan; YALÇIN TOKGÖZ, SİBEL; BAYRAM, HASAN; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Bölümü; 0000-0002-0243-8263; 0000-0001-8106-6834; AAE-9745-2020; JAC-6018-2023
    In this paper, various features of a new class of normalized multivalent harmonic functions in the open unit disk are analyzed, including bounds on coefficients, growth estimations, starlikeness and convexity radii. It is further demonstrated that this class is closed when its members are convoluted. It can also be seen that various previously introduced and investigated classes of multivalent harmonic functions appear as special cases for this class.

    Q-analogue of a new subclass of harmonic univalent functions associated with subordination
    (MDPI, 2022-04-01) Bayram, Hasan; BAYRAM, HASAN; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Matematik Bölümü; 0000-0001-8106-6834; JAC-6018-2023
    In this article, we introduce and investigate the q-analogue of a new subclass of harmonic univalent functions defined by subordination. We first obtain a coefficient characterization of these functions. We give compactness and extreme points, distortion bounds, necessary and sufficient convolution conditions for this subclass of harmonic univalent functions with negative coefficients. The symmetry properties and other properties of the q-analogue subclass of functions presented in this paper shed light on future studies.
