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).

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.

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 ...

Results Related to the Sharp Coefficients Bounds for Symmetric Convex Functions Connected With the Sigmoid Function

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A challenging task in studying geometric function theory is determining the sharp estimates for coefficient‐related results that come up in the Taylor series of analytic univalent functions. In the current paper, we attempt to establish some estimates of results concerning coefficient inequalities for the class of convex functions with respect to ...

Coefficient Bounds and Fekete–Szegö Inequalities for a New Family of Bi‐Univalent Functions Associated With Horadam Polynomial

Journal of Mathematics, Volume 2026, Issue 1, 2026.
We define in this paper a new class of normalized bi‐univalent functions through Horadam polynomials. The main aim of this paper is to provide sharp estimates for the second and third Taylor–Maclaurin coefficients of functions in this new class. We also obtain the Fekete–Szegö inequality for these functions.

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 ...

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 study of analytic functions along with Poisson distribution

Applied Mathematics in Science and Engineering
In this paper, we introduce some new families of analytic functions by using Hadamard product while keeping conic like domains in view. Like the area theorem, we determine sufficient conditions as well as characterizations of these functions. Furthermore,
