In this paper, we introduce the generalized Saitoh operator Lp(a, c, η) and using this operator, the new subclasses H of the class of multivalent functions denoted by Ap(n) are defined. Further for functions belonging to these classes, certain properties of neighborhoods are studied.

Let A p be the class of analytic functions f which are of the form f (z) = z p + ∞ m=p+1 a m z m , (p ∈ N = {1, 2, 3, ...}), defined in the open unit disk U = {z ∈ C : |z| < 1}. We introduce the class M(α, β, n, p) and also the subclass M (α, β, n, p). The aim of the present paper is to derive some convolution properties for functions belonging to the class… (More)

In this paper, we introduce the generalized integral operator J p (σ, λ) and using this generalized integral operator, the new subclasses H of the class of multivalent functions denoted by T p (n) are defined. Further for functions belonging to these classes, certain properties of neighborhoods of functions of complex order are studied.

In this note, we introduce the new operator D p (λ, q, η). Using this operator, we define the new subclasses of analytic and multivalent functions and for functions belonging to these classes, certain (n, δ)-neighborhood properties are obtained.

In this paper we define generalized differential operators from some wellknown operators on the class A(p) of analytic functions in the unit disk ∆ = {z ∈ C : |z| < 1}. New class containing these operators is investigated. Also univalence of integral operator is considered.
