Radius of Strongly Starlikeness for Certain Analytic Functions
For analytic functions f (z) = z p +a p+1 z p+1 +··· in the open unit disk U and a polynomial Q(z) of degree n > 0, the function F(z) = f (z)[Q(z)] β/n is introduced. The object of the present paper is to determine the radius of p-valently strongly starlikeness of order γ for F(z).
متن کاملRadius of p-valent Strong Starlikeness for Certain Class of Analytic Functions
This paper deals with p-valent strongly starlikeness of the class SP (α,A,B) satisfying the subordination e zf ′(z) f(z) ≺ cos z 1 +Az 1 +Bz + i sin α, f ∈ A, z ∈ ∆, 0 ≤ α < 1, −1 ≤ B < A ≤ 1. We are concerned with computing the radius results for the above mentioned class and the results that we obtained are generalizations of earlier results obtained previously by different authors.

متن کاملStarlikeness of Hadamard product of certain analytic functions
An interesting criterion was given by Lashin (A.Y. Lashin, Some convolution properties of analytic functions, Appl. Math. Lett. 18 (2005) 135–138) to be starlike for convolution of analytic functions f, g such that Re1⁄2f 0ðzÞ P a; Re1⁄2g0ðzÞ P b; a; b < 1 in the unit disc U. In this paper we shall improve this criterion. 2007 Elsevier Inc. All rights reserved.
متن کاملCertain Conditions for Starlikeness of Analytic Functions of Koebe Type
For α ≥ 0, λ > 0, we consider theM α, λ b of normalized analytic α−λ convex functions defined in the open unit disc U. In this paper, we investigate the classM α, λ b, that is, Re{ zf ′ b z /fb z 1− α α 1 − λ zf ′ b z /fb z αλ 1 zf ′′ b z /f ′ b z } > 0, with fb is Koebe type, that is, fb z : z/ 1−zn . The subordination result for the aforementioned class will be given. Further, bymaking use of...
