Univalence of certain integral operators
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 10, Page 697-701, 2000., 2000 We study some integral operators and determine conditions for the univalence of these integral operators.

Journal of Function Spaces, Volume 2025, Issue 1, 2025.This article investigates the upper bounds of the second Hankel and Toeplitz determinants for a family of q‐starlike functions defined by a q‐analog integral operator, which is a more general form of the q‐Srivastava‐Attiya operator, and the q‐exponential function eq(z).

On certain sufficient conditions for starlikeness
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 8, Page 521-527, 2000., 2000 We consider certain properties of f(z)f″(z)/f′2(z) as a sufficient condition for starlikeness.

Bi‐Starlike Function of Complex Order Involving Rabotnov Function Associated With Telephone Numbers
Journal of Mathematics, Volume 2025, Issue 1, 2025.Telephone numbers defined through the recurrence relation Qn=Qn−1+n−1Qn−2 for n ≥ 2, with initial values of Q0=Q1=1. The study of such numbers has led to the establishment of various classes of analytic functions associated with them. In this paper, we establish two new subclasses of bi‐convex and bi‐starlike functions of complex order in the open unit

Some sufficient conditions for strongly starlikeness
International Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 9, Page 643-647, 2000., 2000 We consider strongly starlikeness of order α of functions f(z) = z + an+1zn+1 + ⋯ which are analytic in the unit disc and satisfy the condition of the form |f′(z)(zf(z))1+μ−1|<λ, 0101<μ<, <λ< .

Some properties of a class of holomorphic functions associated with tangent function
Demonstratio MathematicaIn this study, we define new class of holomorphic functions associated with tangent function. Furthermore, we examine the differential subordination implementation results related to Janowski and tangent functions. Also, we investigate some extreme point

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

Application of Differential Subordinations to the Arithmetic–Geometric Means by Using an Operator
Journal of Mathematics, Volume 2025, Issue 1, 2025.This study investigates differential subordination involving arithmetic and geometric mean approaches associated with a previously introduced operator. While earlier studies considered cases where the dominant function was convex or linear, the present work extends these results by examining differential subordinations for specific classes of convex ...
