Coefficient Bounds and Fekete-Szego Inequalities for a Subclass of Bi-Univalent Functions Defined via ϱ Neutrosophic-Poisson Distribution [PDF]

Neutrosophic Sets and Systems
In the present study, we introduce a new subclass of bi-univalent analytic functions defined on the open unit disk , generated via the generalized neutrosophic-Poisson distribution (NqPD) series in conjunction with the structural framework of the ...

Fekete–Szegö Inequality for Bi-Univalent Functions Subordinate to Horadam Polynomials

Journal of Function Spaces, 2022
Making use of Horadam polynomials, we propose a special family of regular functions of the type gz=z+∑j=2∞djzj which are bi-univalent (or bi-schlicht) in the disc z∈ℂ ...

Initial Coefficient Bounds for Certain New Subclasses of bi-Bazilevič Functions and Exponentially bi-Convex Functions with Bounded Boundary Rotation

Axioms, 2023
The objective of the present article is to introduce new subclasses of bi-Bazilevič functions, bi-quasi-convex functions and α-exponentially bi-convex functions involving functions with bounded boundary rotation of order ν.

Prediction‐Guided Two‐Step Solid‐State Exploration of Unknown Pseudo‐Ternary Oxides

Advanced Intelligent Discovery, EarlyView.
Prediction‐guided selection combined with two‐step solid‐state exploration enables efficient search of unknown pseudo‐ternary oxides. Broad robotic slurry screening followed by manual single‐phase isolation leads to the discovery of a new oxide, Ba5SnV6O22, showing how data‐guided experiments connect unexplored composition regions to new materials ...

Coefficient problem for certain subclasses of bi-univalent functions defined by convolution [PDF]

Mathematica Moravica, 2016
In this paper, we consider a general subclass HλΣ (h, β) of bi-univalent functions. Bounds on the first two coefficients اa2ا and اa3ا for functions in HλΣ (h, β) are given. The main results generalize and improve a recent one obtained by Srivastava [18].

Euler Polynomials and Bi-univalent Functions

European Journal of Pure and Applied Mathematics
Our 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 ...

Evaluating the (comparative) safety profile of the novel oral polio vaccine type 2 using individual case safety reports in VigiBase

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.

Exploring Fekete-Szegő inequalities for an admissible class of bi-univalent functions involved Gegenbauer polynomials

Arab Journal of Basic and Applied Sciences
This paper presents a newly defined subclass of bi-univalent functions linked to the Genenbauer polynomial. The functions in this subclass satisfy specific subordination conditions within a symmetric domain inside the open unit disk.
