On certain class of meromorphic univalent functions with positive coefficients defined by Dziok-Srivastava operator [PDF]

open access: yes, 2016
In this paper, we introduce a new class of meromorphic univalent functions defined by using Dziok-Srivastava operator and obtain some results including coefficient inequality, growth and distortion theorems and modified Hadamard products.

Subclass of analytic functions on q-analogue connected with a new linear extended multiplier operator [PDF]

open access: yes
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 estimates and Fekete-Szegö problem for some classes of univalent functions generalized to a complex order

open access: yesDemonstratio Mathematica
In this article, we determine coefficient estimates and study the Fekete-Szegö problem for classes Λn(b){\Lambda }_{n}\left(b) and Λnc(b){\Lambda }_{n}^{c}\left(b), where bb is a nonzero complex order.

Some Growth and Distortion Theorems for Close-to-Convex Harmonic Functions in the Unit Disc [PDF]

open access: yes, 2010
MSC 2010: 30C45, 30C55One of the most important questions in the study of the classes of such functions is related to bounds on the modulus of functions (growth) or modulus of the derivative (distortion).

Fekete–Szegö problems for (β, Φ)-spirllike mapping of complex order γ in Banach space

open access: yesDemonstratio Mathematica
In this paper, we establish the sharp Fekete–Szegö inequalities of functional type over a new class of holomorphic mappings on the unit ball in a complex Banach space. This class includes some important widely studied classes. We offer simpler proofs and
