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

Demonstratio 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

A new family of multivalent functions defined by certain forms of the quantum integral operator

Demonstratio Mathematica
In this work, using the concepts of qq-calculus, we first define the qq-Jung-Kim-Srivastava and qq-Bernardi integral operators for multivalent functions. Then, we use these operators to establish the generalized integral operator ℬq,p−m−λf(z){{\mathcal{ {

Subordination and superordination results for the family of Jung-Kim-Srivastava integral operators

, 2010
In this paper, we derive some subordination and superordination results associated with the family of Jung-Kim-Srivastava integral operators defined on the space of meromorphic functions. Several sandwich-type results are also obtained.

Pascu-type p-valent functions associated with the convolution structure [PDF]

, 2015
Making use of convolution structure, we introduce a new class of pvalent functions. Among the results presented in this paper include the coecient bounds, distortion inequalities, extreme points and integral means inequalities for this generalized class ...

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

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.

Starlikeness and close-to-convexity involving certain differential inequalities

In the present paper, we study certain differential inequalities involving meromorphic functions in the open unit disk and obtain certain sufficient conditions for starlikeness and close-to-convexity of meromorphic functions.
