In this research paper, we utilize the q-derivative concept to formulate specific differential and integral operators denoted as Rqn,m,λ, Fqn,m,λ and Gqn,m,λ. These operators are introduced with the aim of generalizing the class of Ruscheweyh oper

The goal of the present investigation is to introduce a new class of analytic functions (Kt,q), defined in the open unit disk, by means of the q-difference operator, which may have symmetric or assymetric properties, and to establish the relationship

Owning to the importance and great interest of differential operators, two generalized differential operators, which may be symmetric or assymetric, are newly introduced in the present paper. Motivated by the familiar Jackson’s second and third Bes

In this paper, two new integral operators are defined using the operator DRλm,n, introduced and studied in previously published papers, defined by the convolution product of the generalized Sălăgean operator and Ruscheweyh operator. The newly defi

In the present paper we introduce sufficient conditions for subordination and superordination involving the operator DRλm,n$DR_\lambda ^{m,n} $ and also we obtain sandwich-type results.

We obtain sufficient conditions for the univalence, starlikeness, and convexity of a new integral operator defined on the space of normalized analytic functions in the open unit disk. Some subordination results for the new integral operator are also

In this paper we obtain coefficient bounds and Fekete–Szego inequalities for a new subclass B α,μ,λ,ω(φ) of analytic functions defined by a new differential operator. Some of our results generalize the related work of some authors. Mathematics

In this paper, we derive sufficient conditions for the univalence, star- likeness, convexity and some other properties in the class N (ρ) ; for a new integral operator defined on the space of normalized analytic functions in the open unit disk.
