On subclasses of M-fold symmetric bi-univalent functions

, 2021
WOS:000637030800028 In this study, we introduce and investigate two new subclasses of the biunivalent functions which both f (z) and f(-1) (z) are m-fold symmetric analytic functions. Among other results, upper bounds for the coefficients vertical bar a(m+1)vertical bar and vertical bar a(2m+1)vertical bar are found in this investigation.

Unveiling the Charge Storage Mechanism of High‐Performance LiV₃O₈ Cathode for Mn2+/H+ Hybrid Batteries

Small, Volume 21, Issue 31, August 7, 2025.
In this study, LiV₃O₈ is explored as a cathode for an aqueous Mn2⁺/H⁺ hybrid battery. It delivers a high capacity of 204.58 mAh g−1 and retains 76.2% after 7000 cycles. Detailed analyses reveal the charge storage mechanism involving proton intercalation and limited Mn2⁺ diffusion due to high migration barriers.

Coefficient estimates for a subclass of bi-univalent functions associated with the Salagean differential operator

Annals of Mathematics and Physics
In this paper, we present and examine a novel subset of the function class ∑, which consists of analytic and bi-univalent functions defined in the open unit disk U and connected to the Salagean differential operator.

Bounds on Initial Coefficients for Bi-Univalent Functions Linked to q-Analog of Le Roy-Type Mittag-Leffler Function

WSEAS Transactions on Mathematics
This study introduces a new class of bi-univalent functions by incorporating the q-analog of Le Roy-type Mittag-Leffler functions alongside q-Ultraspherical polynomials.

A new general subclass of analytic bi-univalent functions

TURKISH JOURNAL OF MATHEMATICS, 2019
In a very recent work, Seker [Seker B. On a new subclass of bi-univalent functions defined by using Salagean operator. Turkish Journal of Mathematics 2018; 42: 2891-2896] defined two subclasses of analytic bi-univalent functions by means of Salagean differential operator and he obtained the initial Taylor-Maclaurin coefficient estimates for functions ...
