New Subclasses of Bi-Univalent Functions Associated with Exponential Functions and Fibonacci Numbers
مجلة بغداد للعلومLewin discussed the class of bi-univalent functions and obtained the bound for the second coefficient, Sakar and Wanas defined two new subclasses of bi-univalent functions and obtained upper bounds for the elementary coefficients |a2| and |a3| for ...

Euler Polynomials and Bi-univalent Functions
European Journal of Pure and Applied MathematicsOur research introduces new subclasses of analytical functions that are defined by Euler polynomials. We then proceed to estimate the Fekete-Szego functional problem and the Maclaurin coefficients for this specific subfamily, denoted as |a2| and |a3|. Furthermore, we demonstrate several new results that emerge when we specialize the parameters used in ...

Coefficient Estimates for New Subclasses of Meromorphic Bi-Univalent Functions [PDF]
International Scholarly Research Notices, 2014 We introduce and investigate two new subclasses Mσα,λ and Mσβ,λ of meromorphic bi-univalent functions defined on Δ={z:z∈C,1<|z|<∞}. For functions belonging to these classes, estimates on the initial coefficients are obtained.

British Journal of Clinical Pharmacology, EarlyView.Aim Novel oral polio vaccine type 2 (nOPV2) was used under the WHO emergency use listing for circulating vaccine‐derived polio virus (cVDPV) outbreaks from 2021 to 2023. We assessed nOPV2 adverse events following immunization (AEFIs) and compared its safety profile to other vaccines using VigiBase.

Coefficient Estimates for a Subclass of Bi-univalent Functions
Communications on Advanced Computational Science with Applications, 2015 In this paper, we consider a subclass $S_{\Sigma}(\alpha,\beta)$ of bi-univalent functions defined in the open unit disk $D=\lbrace z\in\mathbb{C}:|z|< 1\rbrace$. Besides, we find upper bounds for the second and third coefficients for functions in this subclass.
