Coefficient Inequalities Related With Apple‐Like Functions

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
Several subfamilies of Ma and Minda starlike and convex functions have been examined differently through individual generating functions in the literature. However, little or no effort has been devoted to subfamily arising from the product of these generating functions.

Radius of starlikeness through subordination [PDF]

, 2023
A normalized function f on the open unit disc is starlike (or convex) univalent if the associated function zf/(z)/f (z) (or 1+zf//(z)/f/(z)) is a function with positive real part.

Comparison of the in vitro antibiofilm activities of otic cleansers against canine otitis externa pathogens

Veterinary Dermatology, Volume 36, Issue 2, Page 148-158, April 2025.
Background – Biofilm production by canine otitis externa (COE) pathogens and resistance development to multiple antimicrobials are commonly reported problems in veterinary practice. The use of adjuvants to disrupt biofilms may be a viable adjunctive therapy.

A q-Rogers–Ramanujan-based characterization of q-bi-bounded turning functions

Demonstratio Mathematica
This study investigates the second Hankel determinant for a specific class of functions associated with the q-Rogers–Ramanujan polynomial. To accomplish this, we introduce a new subclass of q-bounded turning functions related to the q-Rogers–Ramanujan ...

Generalized q-Srivastava-Attiya operator on multivalent functions [PDF]

In this article, we define a generalized q-integral operator on multivalent functions. It generalizes many known linear operators in Geometric Function Theory (GFT).

Geometric Properties of New Subclasses of Meromorphic Harmonic Functions Associated With Janowski Functions Defined by q‐Calculus

Journal of Function Spaces, Volume 2025, Issue 1, 2025.
This paper establishes new applications of q‐calculus for meromorphic harmonic functions, utilizing concepts of convolutions, subordination, and the q‐difference operator. We introduce the q‐Ruscheweyh‐type derivative operator for meromorphic harmonic functions and utilize it to define and explore novel subclasses related to Janowski functions.

On Certain Improvements on Coefficient Bounds for a Subclass of Convex Functions Associated With Cosine Functions

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this article, we have studied the class Ccos of normalized analytic functions f satisfying 1 + zf″(z)/f′(z)≺cos(z). We present the improved coefficient bounds and the Hankel determinants of fourth order for functions lying in the class Ccos. We also extended the same results for the inverse function.

Fekete-Szegö and Hankel inequalities related to the sine function

Applied Mathematics in Science and Engineering
The Fekete-Szegö inequality is one of the inequalities for the coefficients which associated with the famous Bieberbach conjecture. Other issues associated with this inequality are determining the Hankel determinant denoted as Hd inequalities which are ...

Faber Polynomial Coefficients and Applications in Analytic Function Class

Journal of Mathematics, Volume 2025, Issue 1, 2025.
Through this paper, by using the subordination definition, the ℘‐analogues Cătaş operator I℘nλ,I, complex order, and biunivalent functions with coefficients introduced by Faber polynomial expansion, we introduced the new class S℘,n∗f,λ,I,ξ,α,ϕ. A Faber polynomial is known as a sequence of polynomials that are used to approximate an analytic function on
