Some operators of fractional calculus and their applications regarding various complex functions analytic in certain domains

open access: yes
In this academic research note, some familiar operators prearranged by fractional-order calculus will first be introduced and various characteristic properties of those operators will next be propounded.

Harmonic close-to-convex mappings associated with Sălăgean q-differential operator

open access: yes
In this paper, we define a new subclass W(n; _; q) of analytic functions and a new subclass W0H (n; _; q) of harmonic functions f = h+g 2 H0 associated with Sălăgean q-differential operator. We prove that a harmonic function f = h+_g belongs to the class

Notes on starlike log-harmonic functions of order α

open access: yes, 2013
For log-harmonic functions f(z) = zh(z)g(z) in the open unit disk U, two subclasses H*LH(α) and G*LH(α) of S*LH(α) consisting of all starlike log-harmonic functions of order α (0 ≤ α < 1) are considered. The object of the present paper is to discuss some

© Hindawi Publishing Corp. ON SOME NEW PROPERTIES OF THE SPHERICAL CURVATURE OF STEREOGRAPHICALLY PROJECTED ANALYTIC CURVES

open access: yes, 2002
We discover new information about the spherical curvature of stereographically projected analytic curves. To do so, we first state formulas for the spherical curva-ture and spherical torsion of the curves on S2 which result after stereographically ...
