Integral representations of bounded starlike functions [PDF]

, 1995
For α ≥ 0 let $ℱ_α$ denote the class of functions defined for |z| 0, and log(1/(1-xz)) if α = 0, against a complex measure on |x| = 1. We study families of starlike functions where zf'(z)/f(z) ranges over a parabola with given focus and vertex. We prove

A Study of Certain Geometric Properties and Hardy Spaces of the Normalized Miller-Ross Function

Mathematics
The main objective of this research is to investigate specific sufficiency criteria for the strongly starlikeness, strongly convexity, starlikeness, convexity and pre-starlikeness of the normalized Miller-Ross function.

A new subclass of the meromorphic harmonic y-starlike functions

, 2011
Recently Bostanci and Ozturk defined a new operator M-n for meromorphic harmonic functions. They introduced new classes of meromorphic harmonic starlike functions in (U) over tilde = (z : vertical bar z vertical bar > 1) using operator M-n. In this work,

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

Annales 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}.

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

Fractal 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
