On the Fekete-Szegö problem for classes of bi-univalent functions

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2014
Let \(\mathcal{S}\) denote the class of univalent functions in the unit disk \(\mathbb{D}\) of the form \(f(z) = z + a_2 z^2 + \cdots\). Following \textit{M. Lewin} [Proc. Am. Math. Soc. 18, 63--68 (1967; Zbl 0158.07802)], the author denotes by \(\sigma\) the class of bi-univalent functions, i.e., the class of functions \(f\) for which both \(f\) and \(

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

Bi-Bazilevič functions of complex order involving Ruscheweyh type q-difference operator

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018
In this paper, we define a new subclass of bi-univalent functions involving q-difference operator in the open unit disk. For functions belonging to this class, we obtain estimates on the first two Taylor-Maclaurin coefficients |a2| and |a3|.

Fibonacci Numbers Related to Some Subclasses of Bi‐Univalent Functions

International Journal of Mathematics and Mathematical Sciences
This research paper introduces the novel subclass of bi‐univalent functions that are connected to Fibonacci numbers. Our main contributions in this study involve establishing constraints on the absolute values of the second coefficient |a2| and the third coefficient |a3| for functions within this specific subclass. In addition, we provide solutions to
