In this paper, we introduce the generalized Saitoh operator Lp(a, c, η) and using this operator, the new subclasses H n,m(a, c, η), L n,m(a, c, η;μ), H n,m (a, c, η) and L n,m (a, c, η;μ) 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 Ap be the class of analytic functions f which are of the form f(z) = z + ∞ ∑ m=p+1 am z , (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 Jp(σ, λ) and using this generalized integral operator, the new subclasses H n,m(b, σ, λ), Ln,m(b, σ, λ;μ), H n,m(b, σ, λ) and L n,m(b, σ, λ;μ) of the class of multivalent functions denoted by Tp(n) are defined. Further for functions belonging to these classes, certain properties of neighborhoods(More)
