A q-Rogers–Ramanujan-based characterization of q-bi-bounded turning functions

open access: yesDemonstratio Mathematica
This study investigates the second Hankel determinant for a specific class of functions associated with the q-Rogers–Ramanujan polynomial. To accomplish this, we introduce a new subclass of q-bounded turning functions related to the q-Rogers–Ramanujan ...

New subclasses of univalent functions on the unit disc in C [PDF]

open access: yes
In this paper we consider a differential operator Gk defined on the family of holomorphic normalized functions H0(U) that can be used in the construction of new subclasses of univalent functions on the unit disc U.

Bi- Starlike function of complex order involving Rabotnov function subordinated to Lucas Balancing polynomial

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Considering the interesting results obtained recently by studying Rabotnov function, in this paper using the normalized Rabotnov function and the concept of subordination related with the Lucas Balancing polynomial, we defined two new subclasses of the ...

Gegenbauer Polynomial Convolution for Bi-Univalent Functions with Applications to Image Enhancement

open access: yes
In this paper, we define a new subclass of bi-univalent functions by using convolution and Gegenbauer polynomials. We obtain the initial coefficient bounds and the Fekete-Szegö inequalities for functions belonging to this subclass.

Application of Hölder Inequality in Generalised Convolutions for Functions with Respect to k-Symmetric Points

open access: yes, 2009
Two classes of univalent functions with respect to k-symmetric points define on the unit disk satisfying the conditions: are given. The two inequalities of the functions belonging to these two classes are the starlike and convex functions with respect to
