Certain sufficient conditions for starlikeness and convexity using a multiplier transformation [PDF]
, 2018 In the present paper, we study a differential subordination involving a multiplier transformation. Selecting different dominants to our main result, we obtain certain sufficient conditions for starlikeness and convexity of analytic functions.

On differential subordinations for a class of analytic functions defined by a linear operator
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 42, Page 2219-2230, 2004., 2004 We obtain several results concerning the differential subordination between analytic functions and a linear operator defined for a certain family of analytic functions which are introduced here by means of these linear operators. Also, some special cases are considered.

Coefficient estimates and subordination properties for certain classes of analytic functions of reciprocal order [PDF]
, 2018 In this work, we determine the coefficient bounds and subordination results for functions in certain subclasses of analytic functions of reciprocal order, which are introduced here by means of a Hadamard product of analytic functions.

Radii of harmonic mapping with fixed second coefficients in the plane [PDF]
, 2018 In this paper we investigate the radii problem for harmonic functions with a fixed coefficient and determine the radii of univalence, stable starlikness, stable convexity, fully starlikness and fully convexity of order α for these type of functions.

Spatial decay estimates for a class of nonlinear damped hyperbolic equations
International Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 1, Page 17-26, 2001., 2001 This paper is concerned with investigating the spatial decay estimates for a class of nonlinear damped hyperbolic equations. In addition, we compare the solutions of two‐dimensional wave equations with different damped coefficients and establish an explicit inequality which displays continuous dependence on this coefficient.

Certain class of m-fold functions by applying Faber polynomial expansions [PDF]
, 2021 In this paper, we introduce new class Σm(µ, λ, γ, β) of m-fold symmet- ric bi-univalent functions. Furthermore, we use the Faber polynomial expansions to find upper bounds for the general coefficients |amk+1|(k >= 2) of functions in the class Σm(µ, λ,

Starlike Functions With Respect to a Boundary Point Connected With Bounded Radius Rotation
Journal of Function Spaces, Volume 2026, Issue 1, 2026.In the current article, we introduce a new subclass of univalent function Gμ with bounded radius rotation. For this new class, the authors establish many interesting relations between these classes and existing classes. Furthermore, authors try to find coefficient estimations for this new subclass.

Subclass of analytic functions on q-analogue connected with a new linear extended multiplier operator [PDF]
Using a new linear extended multiplier q-Choi-Saigo-Srivastava operator we define a subclass subordination and the newly defined q-analogue of the Choi-Saigo-Srivastava operator to the class of analytic functions.

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.
