On a Subclass of Certain Starlike Functions With Negative Coefficients

On sandwich theorems for multivalent functions involving a generalized differential operator

“…where the operator D n λ (f * g) was introduced by Aouf and Mostafa [11] and D n 1,p = D n p is the p-valent Sălăgean operator which was introduced and studied by Kamali and Orhan [13] (see also [14]) (ii) For n = 0 and…”

Neighborhoods of a certain class of analytic functions with negative coefficients

“…The classes P(n, λ, αr) and P(n, λ, αr, r) were studied by O.Altintas [3] and M.Kamali et al [4], respectively. P γ (n, λ, α, r) was introduced by M.Kamali et al [5]. The class…”

Majorization for certain classes of analytic functions defined by convolution structure

“…, where the operator I m p (λ, ) was introduced and studied by Cȃtaş [4], which contains intern the operators D m p , (see [2] and [8]) and D m λ (see [1]…”
