چکیده

Abstract The aim of this paper is to investigate various inclusion relations and some other properties of a certain subclasses Λp,k(α,A,B, n) and Λ ∗ p,k(α,A,B, n) of meromorphically p-valent analytic funtions with negative coefficients which are defined here by means of a linear operator. The familier concept of neighborhoods of analytic functions is also extended and applied to the functions considered here. We also derive many interesting results for the modified Hadamard products of functions belonging to the class Λ∗p,k(α,A,B, n).

On Certain Subclasses of Meromorphically p-Valent Functions Associated by the Linear Operator Dn

The purpose of this paper is to introduce two novel subclasses Γλ n, α, β and Γλ n, α, β of meromorphic p-valent functions by using the linear operator D λ . Then we prove the necessary and sufficient conditions for a function f in order to be in the new classes. Further we study several important properties such as coefficients inequalities, inclusion properties, the growth and distortion theo...

Abstract. In this paper, we introduce and investigate the various properties and characteristics of the classMa,c(p;β;A,B) and its subclassM + a,c(p; β;A,B) of meromorphically p-valent functions of order β(pβ > 1), which are defined by means of the Liu-Srivastava operator. In particular, several inclusion relations, coefficients estimates, distortion theorems ,neighborhoods partial, Hadamard pr...

Certain subclasses of bi-univalent functions associated with the Aghalary-Ebadian-Wang operator

In this paper, we introduce and investigate two new subclasses of the functions class $ Sigma $ of bi-univalent functions defined in the open unit disk, which are associated with the Aghalary-Ebadian-Wang operator. We  estimate the coefficients $|a_{2} |$ and  $|a_{3} |$ for functions in these new subclasses. Several  consequences of the result are also pointed out.
