In this paper, by making use of a certain family of fractional derivative operators in the
complex domain, we introduce and investigate a new subclass 𝓟 τ, μ (k, δ, γ) of analytic and …

Making use of certain operators of fractional calculus, we introduce a new class Fδ (n, λ, α)
of functions which are analytic in the open unit disk μ and obtain a necessary and sufficient …

In this paper we have introduced two new classes HR p (β, λ, k, v), HR p¯(β, λ, k, v) of
complex valued harmonic multivalent functions of the form f= h+ g¯, where ℎ and 𝑔 are …

In this paper, we introduce the subclass $ SHP^{-m}(\alpha,\beta) $ using integral operator
