Initial Coefficients Upper Bounds for Certain Subclasses of Bi-Prestarlike Functions
Axioms, 2023 In this article, we introduce and study the behavior of the modules of the first two coefficients for the classes NΣ(γ,λ,δ,μ;α) and NΣ*(γ,λ,δ,μ;β) of normalized holomorphic and bi-univalent functions that are connected with the prestarlike functions.

Journal of Taibah University for Science, 2020 Here in our paper, we present two new subclasses of multivalent analytic functions and complex order by using q–p-valent Cătaş operator. Also we obtain coefficient estimates and consequent inclusion relationships involving the $N_{i,\delta }^{\mathbf {p}

Coefficient estimates for Ruscheweyh derivatives
International Journal of Mathematics and Mathematical Sciences, 2004 We consider functions f, analytic in the unit disc and of the normalized form f(z)=z+∑n=2∞anzn. For functions f∈R¯δ(β), the class of functions involving the Ruscheweyh derivatives operator, we give sharp upper bounds for the Fekete-Szegö functional |a3 ...

On Coefficient Estimates for a Certain Class of Analytic Functions
Mathematics, 2022 In this paper, we consider a subclass SQ of normalized analytic functions f satisfying ℜf′(z)>1/2. For the functions in the class SQ, we determine upper bounds for a number of coefficient estimates, among which are initial coefficients, the second Hankel

Coefficient Estimates of New Families of Analytic Functions Associated with q-Hermite Polynomials
Axioms, 2023 In this paper, we introduce two new subclasses of bi-univalent functions using the q-Hermite polynomials. Furthermore, we establish the bounds of the initial coefficients υ2, υ3, and υ4 of the Taylor–Maclaurin series and that of the Fekete–Szegö ...
