نویسندگان

چکیده

In this paper, we define and discuss properties of various classes analytic univalent functions by using modified q-Sigmoid functions. We make use an idea Salagean to introduce the q-analogue differential operator. addition, derive families associated with new q-Salagean q-Ruscheweh operators. obtain coefficient bounds for in such subclasses establish certain growth distortion theorems. By concept (q, ?)-neighbourhood, provide several inclusion symmetric relations ?)-neighbourhoods negative coefficients. Various q-inequalities are also discussed more details.

Coefficient Estimates for a Subclass of Bi-univalent Functions Defined by Salagean Operator Using Quasi Subordination

In this present investigation, we consider the subclass of analytic and bi-univalent functions associated with salagean operator consisting of the function class Σ in the unit open disk, which satisfies the qusi-subordination conditions. Also we obtain the first two Taylor-Maclaurin coefficients for functions in this new subclass. Mathematics Subject Classification: 30C45, 30C50

Certain subclass of $p$-valent meromorphic Bazilevi'{c} functions defined by fractional $q$-calculus operators

The aim of the present paper is to introduce and investigate a new subclass of Bazilevi'{c} functions in the punctured unit disk $mathcal{U}^*$ which have been described through using of the well-known fractional $q$-calculus operators, Hadamard product and a linear operator. In addition, we obtain some sufficient conditions for the func...

Generalized Salagean-type harmonic univalent functions

The main purpose of this paper is to introduce a generalization of modified Salagean operator for harmonic univalent functions. We define a new subclass of complex-valued harmonic univalent functions by using this operator ,and we investigate necessary and sufficient coefficient conditions, distortion bounds, extreme points and convex combination for the above class of harmonic univalent functi...
