Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 In this paper, we introduce a new derivative operator involving q‐Al‐Oboudi differential operator for meromorphic functions. By using this new operator, we define a new subclass of meromorphic functions and obtain the Fekete–Szegő inequalities.

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 In this work, we introduce and investigate a new subclass of analytic bi‐univalent functions based on subordination conditions between the zero‐truncated Poisson distribution and Gegenbauer polynomials. More precisely, we will estimate the first two initial Taylor–Maclaurin coefficients and solve the Fekete–Szegö functional problem for functions ...

Some Properties of Bazilevič Functions Involving Srivastava–Tomovski Operator [PDF]
, 2022 We introduce a new class of Bazilevič functions involving the Srivastava–Tomovski generalization of the Mittag-Leffler function. The family of functions introduced here is superordinated by a conic domain, which is impacted by the Janowski function.

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 In recent years, the usage of the q‐derivative and symmetric q‐derivative operators is significant. In this study, firstly, many known concepts of the q‐derivative operator are highlighted and given. We then use the symmetric q‐derivative operator and certain q‐Chebyshev polynomials to define a new subclass of analytic and bi‐univalent functions.

Hankel and Symmetric Toeplitz Determinants for a New Subclass of q-Starlike Functions
Fractal and Fractional, 2022 This paper considers the basic concepts of q-calculus and the principle of subordination. We define a new subclass of q-starlike functions related to the Salagean q-differential operator.

Fekete–Szegö Functional Problem for a Special Family of m-Fold Symmetric Bi-Univalent Functions
Mathematics, 2022 In the current work, we introduce a special family of the function family of analytic and m-fold symmetric bi-univalent functions and obtain estimates of the Taylor–Maclaurin coefficients |dm+1| and |d2m+1| for functions in the special family.

Some Sharp Results on Coefficient Estimate Problems for Four‐Leaf‐Type Bounded Turning Functions
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In this study, we focused on a subclass of bounded turning functions that are linked with a four‐leaf‐type domain. The primary goal of this study is to explore the limits of the first four initial coefficients, the Fekete‐Szegö type inequality, the Zalcman inequality, the Kruskal inequality, and the estimation of the second‐order Hankel determinant for
