In the current study, we look at the majorization characteristics of the subclass U m (α, η, δ)
of analytical functions described by the fractional Ruscheweyh–Goyal derivative. There are …

In the present paper, we define a new class NA (n, p, λ, α, β) of multivalent functions which
are holomorphic in the unit disk∆={s∈ C∶| s|< 1}. A necessary and sufficient condition for …
