Characterization of p-valent q-starlike functions through Hadamard product and Poisson distribution

open access: yesApplied Mathematics in Science and Engineering
This paper presents significant advancement in the study of multivalent functions by introducing three new subclasses of p-valent q-starlike functions, defined with respect to higher-order q-derivatives within the open unit disk of the complex plane ...

On classes of ζ-uniformly q-analogue of analytic functions with some subordination results

open access: yesApplied Mathematics in Science and Engineering
This article presents new classes of ζ-uniformly q-starlike and q-convex analytic functions of order υ using the principle of q-calculus. The renowned classes of starlike and convex functions are utilized to establish these classes.

Some Geometric Characterizations of a Certain Class of Log-Harmonic Mappings

open access: yesMathematics
This article investigates structural properties of a class of log-harmonic mappings associated with starlike analytic functions in the unit disk. Beginning with a general representation of the log-harmonic mappings, we use sharp inequalities using ...

On a subclass of n-starlike functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
In 1999, Kanas and Rønning introduced the classes of starlike and convex functions, which are normalized with f(w)=f'(w)−1=0 and w a fixed point in U.

Starlikeness associated with parabolic regions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
A parabolic starlike function f of order ρ in the unit disk is characterized by the fact that the quantity zf′(z)/f(z) lies in a given parabolic region in the right half-plane. Denote the class of such functions by PS∗(ρ).

Sharp Bounds on Hankel Determinant of q-Starlike and q-Convex Functions Subordinate to Secant Hyperbolic Functions

open access: yesFractal and Fractional
In the present paper, using the q-difference operator, we introduce two classes of q-starlike functions and q-convex functions subordinate to secant hyperbolic functions. As functions in these classes have unique characteristic of missing coefficients on

Starlike functions of complex order involving q-hypergeometric functions with fixed point

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2014
Recently Kanas and Ronning introduced the classes of starlike and convex functions, which are normalized with f(ksi)=f'(ksi)-1=0, ksi (|ksi|=d) is a fixed point in the open disc U ={z C:|z| 1}.
