Argument Estimates of Certain Meromorphically p-Valent Functions DeÂ…fined by a Linear Operator	2017	13	.pdf	application/pdf	3965	215	87	[11], for a function f (z) ∈ Σp,n given by (1), we now define a linear operator Dm λ,p (λ≥ 0, p ∈ N, m ∈ N0 = N∪ {0}) by D0 λ,p f (z) = f (z) D1 λ,p f (z) =Dλ,p f (z) = (1−λ) Using the identity (6), we have (p− γ)zq′(z)Dm λ,p g(z) + (p− γ)q(z)z(Dm λ,p f (z))′+ γz(Dm λ,p g(z))′ = 1+λp λ z(Dm λ,p f (z))′− 1 λ z(Dm+1 λ,p f (z))′. (20) Simplifying (20), we obtain q(z) + zq′(z) −r(z) + 1+λp λ =− 1 p− γ z(Dm+1 λ,p f (z))′ Dm+1 λ,p g(z) + γ ! , (21)	cache/ejpam-1074.pdf	txt/ejpam-1074.txt
